+
+  For each key, if the key does not exist, it is created. If it already
+  exists and it was inherited from its constructor, the constructor's

+
+  If you return a value from the `before` callback, that same
+  value will be passed as a fourth parameter to the `after`
+  callback.
+
+  Instrument a block of code by using `Ember.instrument`:
+
+  ```javascript
+  Ember.instrument("render.handlebars", payload, function() {
+    // rendering logic
+  }, binding);
+  ```
+
+  Event names passed to `Ember.instrument` are namespaced

+  can listen for events by whatever level of granularity they
+  are interested in.
+
+  In the above example, the event is `render.handlebars`,
+  and the subscriber listened for all events beginning with
+  `render`. It would receive callbacks for events named
+  `render`, `render.handlebars`, `render.container`, or

+  control has been returned to the system. This is equivalent to calling
+  `Ember.run.later` with a wait time of 1ms.
+
+  ```javascript
+  Ember.run.next(myContext, function(){
+    // code to be executed in the next run loop, which will be scheduled after the current one
+  });
+  ```
+
+  Multiple operations scheduled with `Ember.run.next` will coalesce
+  into the same later run loop, along with any other operations
+  scheduled by `Ember.run.later` that expire right around the same
+  time that `Ember.run.next` operations will fire.
+
+  Note that there are often alternatives to using `Ember.run.next`.
+  For instance, if you'd like to schedule an operation to happen
+  after all DOM element operations have completed within the current
+  run loop, you can make use of the `afterRender` run loop queue (added
+  by the `ember-views` package, along with the preceding `render` queue
+  where all the DOM element operations happen). Example:
+
+  ```javascript
+  App.MyCollectionView = Ember.CollectionView.extend({
+    didInsertElement: function() {
+      Ember.run.scheduleOnce('afterRender', this, 'processChildElements');
+    },
+    processChildElements: function() {
+      // ... do something with collectionView's child view
+      // elements after they've finished rendering, which
+      // can't be done within the CollectionView's
+      // `didInsertElement` hook because that gets run
+      // before the child elements have been added to the DOM.
+    }
+  });
+  ```
+
+  One benefit of the above approach compared to using `Ember.run.next` is
+  that you will be able to perform DOM/CSS operations before unprocessed
+  elements are rendered to the screen, which may prevent flickering or
+  other artifacts caused by delaying processing until after rendering.
+
+  The other major benefit to the above approach is that `Ember.run.next`
+  introduces an element of non-determinism, which can make things much
+  harder to test, due to its reliance on `setTimeout`; it's much harder
+  to guarantee the order of scheduled operations when they are scheduled
+  outside of the current run loop, i.e. with `Ember.run.next`.

+/**
+  An `Ember.Binding` connects the properties of two objects so that whenever
+  the value of one property changes, the other property will be changed also.
+
+  ## Automatic Creation of Bindings with `/^*Binding/`-named Properties
+
+  You do not usually create Binding objects directly but instead describe
+  bindings in your class or object definition using automatic binding
+  detection.
+
+  Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
+  instances. The value of this property should be a string representing a path
+  to another object or a custom binding instanced created using Binding helpers
+  (see "One Way Bindings"):
+
+  ```
+  valueBinding: "MyApp.someController.title"
+  ```
+
+  This will create a binding from `MyApp.someController.title` to the `value`
+  property of your object instance automatically. Now the two values will be
+  kept in sync.
+
+  ## One Way Bindings
+
+  One especially useful binding customization you can use is the `oneWay()`
+  helper. This helper tells Ember that you are only interested in
+  receiving changes on the object you are binding from. For example, if you
+  are binding to a preference and you want to be notified if the preference
+  has changed, but your object will not be changing the preference itself, you
+  could do:
+
+  ```
+  bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
+  ```
+
+  This way if the value of `MyApp.preferencesController.bigTitles` changes the
+  `bigTitles` property of your object will change also. However, if you
+  change the value of your `bigTitles` property, it will not update the
+  `preferencesController`.
+
+  One way bindings are almost twice as fast to setup and twice as fast to
+  execute because the binding only has to worry about changes to one side.
+
+  You should consider using one way bindings anytime you have an object that
+  may be created frequently and you do not intend to change a property; only
+  to monitor it for changes (such as in the example above).
+
+  ## Adding Bindings Manually
+
+  All of the examples above show you how to configure a custom binding, but the
+  result of these customizations will be a binding template, not a fully active
+  Binding instance. The binding will actually become active only when you
+  instantiate the object the binding belongs to. It is useful however, to
+  understand what actually happens when the binding is activated.
+
+  For a binding to function it must have at least a `from` property and a `to`
+  property. The `from` property path points to the object/key that you want to
+  bind from while the `to` path points to the object/key you want to bind to.
+
+  When you define a custom binding, you are usually describing the property
+  you want to bind from (such as `MyApp.someController.value` in the examples
+  above). When your object is created, it will automatically assign the value
+  you want to bind `to` based on the name of your binding key. In the
+  examples above, during init, Ember objects will effectively call
+  something like this on your binding:
+
+  ```javascript
+  binding = Ember.Binding.from(this.valueBinding).to("value");
+  ```
+
+  This creates a new binding instance based on the template you provide, and
+  sets the to path to the `value` property of the new object. Now that the
+  binding is fully configured with a `from` and a `to`, it simply needs to be
+  connected to become active. This is done through the `connect()` method:
+
+  ```javascript
+  binding.connect(this);
+  ```
+
+  Note that when you connect a binding you pass the object you want it to be
+  connected to. This object will be used as the root for both the from and
+  to side of the binding when inspecting relative paths. This allows the
+  binding to be automatically inherited by subclassed objects as well.
+
+  Now that the binding is connected, it will observe both the from and to side
+  and relay changes.
+
+  If you ever needed to do so (you almost never will, but it is useful to
+  understand this anyway), you could manually create an active binding by
+  using the `Ember.bind()` helper method. (This is the same method used by
+  to setup your bindings on objects):
+
+  ```javascript
+  Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
+  ```
+
+  Both of these code fragments have the same effect as doing the most friendly
+  form of binding creation like so:
+
+  ```javascript
+  MyApp.anotherObject = Ember.Object.create({
+    valueBinding: "MyApp.someController.value",
+
+    // OTHER CODE FOR THIS OBJECT...
+  });
+  ```
+
+  Ember's built in binding creation method makes it easy to automatically
+  create bindings for you. You should always use the highest-level APIs
+  available, even if you understand how it works underneath.

+
+    Treating a function like a property is useful because they can work with
+    bindings, just like any other property.
+
+    Many computed properties have dependencies on other properties. For
+    example, in the above example, the `fullName` property depends on

+    about these dependencies like this:
+

+
+    Make sure you list these dependencies so Ember knows when to update

+  This mixin defines the common interface implemented by enumerable objects
+  in Ember. Most of these methods follow the standard Array iteration
+  API defined up to JavaScript 1.8 (excluding language-specific features that
+  cannot be emulated in older versions of JavaScript).
+
+  This mixin is applied automatically to the Array class on page load, so you
+  can use any of these methods on simple arrays. If Array already implements
+  one of these methods, the mixin will not override them.
+
+  ## Writing Your Own Enumerable
+
+  To make your own custom class enumerable, you need two items:
+
+  1. You must have a length property. This property should change whenever
+     the number of items in your enumerable object changes. If you using this
+     with an `Ember.Object` subclass, you should be sure to change the length
+     property using `set().`
+
+  2. If you must implement `nextObject().` See documentation.
+
+  Once you have these two methods implement, apply the `Ember.Enumerable` mixin
+  to your class and you will be able to enumerate the contents of your object
+  like any other collection.
+
+  ## Using Ember Enumeration with Other Libraries
+
+  Many other libraries provide some kind of iterator or enumeration like
+  facility. This is often where the most common API conflicts occur.
+  Ember's API is designed to be as friendly as possible with other
+  libraries by implementing only methods that mostly correspond to the
+  JavaScript 1.8 API.

+    Implement this method to make your class enumerable.
+
+    This method will be call repeatedly during enumeration. The index value
+    will always begin with 0 and increment monotonically. You don't have to
+    rely on the index value to determine what object to return, but you should
+    always check the value and start from the beginning when you see the
+    requested index is 0.
+
+    The `previousObject` is the object that was returned from the last call
+    to `nextObject` for the current iteration. This is a useful way to
+    manage iteration if you are tracing a linked list, for example.
+
+    Finally the context parameter will always contain a hash you can use as
+    a "scratchpad" to maintain any other state you need in order to iterate
+    properly. The context object is reused and is not reset between
+    iterations so make sure you setup the context with a fresh state whenever
+    the index parameter is 0.
+
+    Generally iterators will continue to call `nextObject` until the index
+    reaches the your current length-1. If you run out of data before this
+    time for some reason, you should simply return undefined.
+
+    The default implementation of this method simply looks up the index.

+/**
+  This module implements Observer-friendly Array-like behavior. This mixin is
+  picked up by the Array class as well as other controllers, etc. that want to
+  appear to be arrays.
+
+  Unlike `Ember.Enumerable,` this mixin defines methods specifically for
+  collections that provide index-ordered access to their contents. When you
+  are designing code that needs to accept any kind of Array-like object, you
+  should use these methods instead of Array primitives because these will
+  properly notify observers of changes to the array.
+
+  Although these methods are efficient, they do add a layer of indirection to
+  your application so it is a good idea to use them only when you need the
+  flexibility of using both true JavaScript arrays and "virtual" arrays such
+  as controllers and collections.
+
+  You can use the methods defined in this module to access and modify array
+  contents in a KVO-friendly way. You can also be notified whenever the
+  membership of an array changes by changing the syntax of the property to
+  `.observes('*myProperty.[]')`.
+
+  To support `Ember.Array` in your own class, you must override two
+  primitives to use it: `replace()` and `objectAt()`.
+
+  Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`
+  mixin. All `Ember.Array`-like objects are also enumerable.

+  The `Ember.Freezable` mixin implements some basic methods for marking an
+  object as frozen. Once an object is frozen it should be read only. No changes
+  may be made the internal state of the object.
+
+  ## Enforcement
+
+  To fully support freezing in your subclass, you must include this mixin and
+  override any method that might alter any property on the object to instead
+  raise an exception. You can check the state of an object by checking the
+  `isFrozen` property.
+
+  Although future versions of JavaScript may support language-level freezing
+  object objects, that is not the case today. Even if an object is freezable,
+  it is still technically possible to modify the object, even though it could
+  break other parts of your application that do not expect a frozen object to
+  change. It is, therefore, very important that you always respect the
+  `isFrozen` property on all freezable objects.
+
+  ## Example Usage
+
+  The example below shows a simple object that implement the `Ember.Freezable`
+  protocol.
+
+  ```javascript
+  Contact = Ember.Object.extend(Ember.Freezable, {
+    firstName: null,
+    lastName: null,
+
+    // swaps the names
+    swapNames: function() {
+      if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;
+      var tmp = this.get('firstName');
+      this.set('firstName', this.get('lastName'));
+      this.set('lastName', tmp);
+      return this;
+    }
+
+  });
+
+  c = Context.create({ firstName: "John", lastName: "Doe" });
+  c.swapNames();  // returns c
+  c.freeze();
+  c.swapNames();  // EXCEPTION
+  ```
+
+  ## Copying
+
+  Usually the `Ember.Freezable` protocol is implemented in cooperation with the
+  `Ember.Copyable` protocol, which defines a `frozenCopy()` method that will
+  return a frozen object, if the object implements this method as well.
+
+  @class Freezable

+  For example, a MappedEnumerable cannot be directly modified but if its
+  underlying enumerable changes, it will change also.
+
+  ## Adding Objects
+
+  To add an object to an enumerable, use the `addObject()` method. This
+  method will only add the object to the enumerable if the object is not
+  already present and is of a type supported by the enumerable.
+
+  ```javascript

+  ```javascript

+
+  ## Implementing In Your Own Code

+/**
+  ## Overview
+
+  This mixin provides properties and property observing functionality, core
+  features of the Ember object model.
+
+  Properties and observers allow one object to observe changes to a
+  property on another object. This is one of the fundamental ways that
+  models, controllers and views communicate with each other in an Ember
+  application.
+
+  Any object that has this mixin applied can be used in observer
+  operations. That includes `Ember.Object` and most objects you will
+  interact with as you write your Ember application.
+
+  Note that you will not generally apply this mixin to classes yourself,
+  but you will use the features provided by this module frequently, so it
+  is important to understand how to use it.
+
+  ## Using `get()` and `set()`
+
+  Because of Ember's support for bindings and observers, you will always
+  access properties using the get method, and set properties using the
+  set method. This allows the observing objects to be notified and
+  computed properties to be handled properly.
+
+  More documentation about `get` and `set` are below.
+
+  ## Observing Property Changes
+
+  You typically observe property changes simply by adding the `observes`
+  call to the end of your method declarations in classes that you write.
+  For example:
+
+  ```javascript
+  Ember.Object.extend({
+    valueObserver: function() {
+      // Executes whenever the "value" property changes
+    }.observes('value')
+  });
+  ```
+
+  Although this is the most common way to add an observer, this capability
+  is actually built into the `Ember.Object` class on top of two methods
+  defined in this mixin: `addObserver` and `removeObserver`. You can use
+  these two methods to add and remove observers yourself if you need to
+  do so at runtime.
+
+  To add an observer for a property, call:
+
+  ```javascript
+  object.addObserver('propertyKey', targetObject, targetAction)
+  ```
+
+  This will call the `targetAction` method on the `targetObject` whenever
+  the value of the `propertyKey` changes.
+
+  Note that if `propertyKey` is a computed property, the observer will be
+  called when any of the property dependencies are changed, even if the
+  resulting value of the computed property is unchanged. This is necessary
+  because computed properties are not computed until `get` is called.
+
+  @class Observable
+  @namespace Ember
+  @extends Ember.Mixin
+*/
+Ember.Observable = Ember.Mixin.create(/** @scope Ember.Observable.prototype */ {
+
+  /**
+    Retrieves the value of a property from the object.
+
+    This method is usually similar to using `object[keyName]` or `object.keyName`,
+    however it supports both computed properties and the unknownProperty
+    handler.
+
+    Because `get` unifies the syntax for accessing all these kinds
+    of properties, it can make many refactorings easier, such as replacing a
+    simple property with a computed property, or vice versa.
+
+    ### Computed Properties
+
+    Computed properties are methods defined with the `property` modifier
+    declared at the end, such as:
+
+    ```javascript
+    fullName: function() {
+      return this.getEach('firstName', 'lastName').compact().join(' ');
+    }.property('firstName', 'lastName')
+    ```
+
+    When you call `get` on a computed property, the function will be
+    called and the return value will be returned instead of the function
+    itself.
+
+    ### Unknown Properties
+
+    Likewise, if you try to call `get` on a property whose value is
+    `undefined`, the `unknownProperty()` method will be called on the object.
+    If this method returns any value other than `undefined`, it will be returned
+    instead. This allows you to implement "virtual" properties that are
+    not defined upfront.
+
+    @method get
+    @param {String} keyName The property to retrieve
+    @return {Object} The property value or undefined.
+  */
+  get: function(keyName) {
+    return get(this, keyName);
+  },
+
+  /**
+    To get multiple properties at once, call `getProperties`
+    with a list of strings or an array:
+
+    ```javascript
+    record.getProperties('firstName', 'lastName', 'zipCode');  // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
+    ```
+
+    is equivalent to:
+
+    ```javascript
+    record.getProperties(['firstName', 'lastName', 'zipCode']);  // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
+    ```
+
+    @method getProperties
+    @param {String...|Array} list of keys to get
+    @return {Hash}
+  */
+  getProperties: function() {
+    var ret = {};
+    var propertyNames = arguments;
+    if (arguments.length === 1 && Ember.typeOf(arguments[0]) === 'array') {
+      propertyNames = arguments[0];
+    }
+    for(var i = 0; i < propertyNames.length; i++) {
+      ret[propertyNames[i]] = get(this, propertyNames[i]);
+    }
+    return ret;
+  },
+
+  /**
+    Sets the provided key or path to the value.
+
+    This method is generally very similar to calling `object[key] = value` or
+    `object.key = value`, except that it provides support for computed
+    properties, the `unknownProperty()` method and property observers.
+
+    ### Computed Properties
+
+    If you try to set a value on a key that has a computed property handler
+    defined (see the `get()` method for an example), then `set()` will call
+    that method, passing both the value and key instead of simply changing
+    the value itself. This is useful for those times when you need to
+    implement a property that is composed of one or more member
+    properties.
+
+    ### Unknown Properties
+
+    If you try to set a value on a key that is undefined in the target
+    object, then the `unknownProperty()` handler will be called instead. This
+    gives you an opportunity to implement complex "virtual" properties that
+    are not predefined on the object. If `unknownProperty()` returns
+    undefined, then `set()` will simply set the value on the object.
+
+    ### Property Observers
+
+    In addition to changing the property, `set()` will also register a property
+    change with the object. Unless you have placed this call inside of a
+    `beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
+    (i.e. observer methods declared on the same object), will be called
+    immediately. Any "remote" observers (i.e. observer methods declared on
+    another object) will be placed in a queue and called at a later time in a
+    coalesced manner.
+
+    ### Chaining
+
+    In addition to property changes, `set()` returns the value of the object
+    itself so you can do chaining like this:
+
+    ```javascript
+    record.set('firstName', 'Charles').set('lastName', 'Jolley');
+    ```
+
+    @method set
+    @param {String} keyName The property to set
+    @param {Object} value The value to set or `null`.
+    @return {Ember.Observable}
+  */
+  set: function(keyName, value) {
+    set(this, keyName, value);
+    return this;
+  },
+
+  /**
+    To set multiple properties at once, call `setProperties`
+    with a Hash:
+
+    ```javascript
+    record.setProperties({ firstName: 'Charles', lastName: 'Jolley' });

+
+  /**
+    Adds an observer on a property.
+
+    This is the core method used to register an observer for a property.
+
+    Once you call this method, any time the key's value is set, your observer
+    will be notified. Note that the observers are triggered any time the
+    value is set, regardless of whether it has actually changed. Your
+    observer should be prepared to handle that.
+
+    You can also pass an optional context parameter to this method. The
+    context will be passed to your observer method whenever it is triggered.
+    Note that if you add the same target/method pair on a key multiple times
+    with different context parameters, your observer will only be called once
+    with the last context you passed.
+
+    ### Observer Methods
+
+    Observer methods you pass should generally have the following signature if
+    you do not pass a `context` parameter:
+
+    ```javascript
+    fooDidChange: function(sender, key, value, rev) { };
+    ```
+
+    The sender is the object that changed. The key is the property that
+    changes. The value property is currently reserved and unused. The rev
+    is the last property revision of the object when it changed, which you can
+    use to detect if the key value has really changed or not.
+
+    If you pass a `context` parameter, the context will be passed before the
+    revision like so:
+
+    ```javascript
+    fooDidChange: function(sender, key, value, context, rev) { };
+    ```
+
+    Usually you will not need the value, context or revision parameters at
+    the end. In this case, it is common to write observer methods that take
+    only a sender and key value as parameters or, if you aren't interested in
+    any of these values, to write an observer that has no parameters at all.
+
+    @method addObserver
+    @param {String} key The key to observer
+    @param {Object} target The target object to invoke
+    @param {String|Function} method The method to invoke.

+    Defines the properties that will be concatenated from the superclass
+    (instead of overridden).
+
+    By default, when you extend an Ember class a property defined in
+    the subclass overrides a property with the same name that is defined
+    in the superclass. However, there are some cases where it is preferable
+    to build up a property's value by combining the superclass' property
+    value with the subclass' value. An example of this in use within Ember
+    is the `classNames` property of `Ember.View`.
+
+    Here is some sample code showing the difference between a concatenated
+    property and a normal one:
+
+    ```javascript
+    App.BarView = Ember.View.extend({
+      someNonConcatenatedProperty: ['bar'],
+      classNames: ['bar']
+    });
+
+    App.FooBarView = App.BarView.extend({
+      someNonConcatenatedProperty: ['foo'],
+      classNames: ['foo'],
+    });
+
+    var fooBarView = App.FooBarView.create();
+    fooBarView.get('someNonConcatenatedProperty'); // ['foo']
+    fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
+    ```
+
+    This behavior extends to object creation as well. Continuing the
+    above example:
+
+    ```javascript
+    var view = App.FooBarView.create({
+      someNonConcatenatedProperty: ['baz'],
+      classNames: ['baz']
+    })
+    view.get('someNonConcatenatedProperty'); // ['baz']
+    view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
+    ```
+    Adding a single property that is not an array will just add it in the array:
+
+    ```javascript
+    var view = App.FooBarView.create({
+      classNames: 'baz'
+    })
+    view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
+    ```
+
+    Using the `concatenatedProperties` property, we can tell to Ember that mix
+    the content of the properties.
+
+    In `Ember.View` the `classNameBindings` and `attributeBindings` properties
+    are also concatenated, in addition to `classNames`.
+
+    This feature is available for you to use throughout the Ember object model,
+    although typical app developers are likely to use it infrequently.

+  An ArrayProxy wraps any other object that implements `Ember.Array` and/or
+  `Ember.MutableArray,` forwarding all requests. This makes it very useful for
+  a number of binding use cases or other cases where being able to swap
+  out the underlying array is useful.
+
+  A simple example of usage:
+
+  ```javascript
+  var pets = ['dog', 'cat', 'fish'];
+  var ap = Ember.ArrayProxy.create({ content: Ember.A(pets) });
+
+  ap.get('firstObject');                        // 'dog'
+  ap.set('content', ['amoeba', 'paramecium']);
+  ap.get('firstObject');                        // 'amoeba'
+  ```
+
+  This class can also be useful as a layer to transform the contents of
+  an array, as they are accessed. This can be done by overriding
+  `objectAtContent`:
+
+  ```javascript
+  var pets = ['dog', 'cat', 'fish'];
+  var ap = Ember.ArrayProxy.create({
+      content: Ember.A(pets),
+      objectAtContent: function(idx) {

+      }
+  });
+
+  ap.get('firstObject'); // . 'DOG'

+/**
+  An unordered collection of objects.
+
+  A Set works a bit like an array except that its items are not ordered. You
+  can create a set to efficiently test for membership for an object. You can
+  also iterate through a set just like an array, even accessing objects by
+  index, however there is no guarantee as to their order.
+
+  All Sets are observable via the Enumerable Observer API - which works
+  on any enumerable object including both Sets and Arrays.
+
+  ## Creating a Set
+
+  You can create a set like you would most objects using
+  `new Ember.Set()`. Most new sets you create will be empty, but you can
+  also initialize the set with some content by passing an array or other
+  enumerable of objects to the constructor.
+
+  Finally, you can pass in an existing set and the set will be copied. You
+  can also create a copy of a set by calling `Ember.Set#copy()`.
+
+  ```javascript
+  // creates a new empty set
+  var foundNames = new Ember.Set();
+
+  // creates a set with four names in it.
+  var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P
+
+  // creates a copy of the names set.
+  var namesCopy = new Ember.Set(names);
+
+  // same as above.
+  var anotherNamesCopy = names.copy();
+  ```
+
+  ## Adding/Removing Objects
+
+  You generally add or remove objects from a set using `add()` or
+  `remove()`. You can add any type of object including primitives such as
+  numbers, strings, and booleans.
+
+  Unlike arrays, objects can only exist one time in a set. If you call `add()`
+  on a set with the same object multiple times, the object will only be added
+  once. Likewise, calling `remove()` with the same object multiple times will
+  remove the object the first time and have no effect on future calls until
+  you add the object to the set again.
+
+  NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do
+  so will be ignored.
+
+  In addition to add/remove you can also call `push()`/`pop()`. Push behaves
+  just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary
+  object, remove it and return it. This is a good way to use a set as a job
+  queue when you don't care which order the jobs are executed in.
+
+  ## Testing for an Object
+
+  To test for an object's presence in a set you simply call
+  `Ember.Set#contains()`.
+
+  ## Observing changes
+
+  When using `Ember.Set`, you can observe the `"[]"` property to be
+  alerted whenever the content changes. You can also add an enumerable
+  observer to the set to be notified of specific objects that are added and
+  removed from the set. See `Ember.Enumerable` for more information on
+  enumerables.
+
+  This is often unhelpful. If you are filtering sets of objects, for instance,
+  it is very inefficient to re-filter all of the items each time the set
+  changes. It would be better if you could just adjust the filtered set based
+  on what was changed on the original set. The same issue applies to merging
+  sets, as well.
+
+  ## Other Methods
+
+  `Ember.Set` primary implements other mixin APIs. For a complete reference
+  on the methods you will use with `Ember.Set`, please consult these mixins.
+  The most useful ones will be `Ember.Enumerable` and
+  `Ember.MutableEnumerable` which implement most of the common iterator
+  methods you are used to on Array.
+
+  Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
+  APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
+  modified. The benefit of this is that when you call `frozenCopy()` on it,
+  Ember will avoid making copies of the set. This allows you to write
+  code that can know with certainty when the underlying set data will or
+  will not be modified.

+/**
+  `Ember.ArrayController` provides a way for you to publish a collection of
+  objects so that you can easily bind to the collection from a Handlebars
+  `#each` helper, an `Ember.CollectionView`, or other controllers.
+
+  The advantage of using an `ArrayController` is that you only have to set up
+  your view bindings once; to change what's displayed, simply swap out the
+  `content` property on the controller.
+
+  For example, imagine you wanted to display a list of items fetched via an XHR
+  request. Create an `Ember.ArrayController` and set its `content` property:
+
+  ```javascript
+  MyApp.listController = Ember.ArrayController.create();
+
+  $.get('people.json', function(data) {
+    MyApp.listController.set('content', data);
+  });
+  ```
+
+  Then, create a view that binds to your new controller:
+
+  ```handlebars
+  {{#each MyApp.listController}}
+    {{firstName}} {{lastName}}
+  {{/each}}
+  ```
+
+  Although you are binding to the controller, the behavior of this controller
+  is to pass through any methods or properties to the underlying array. This
+  capability comes from `Ember.ArrayProxy`, which this class inherits from.
+
+  Sometimes you want to display computed properties within the body of an
+  `#each` helper that depend on the underlying items in `content`, but are not
+  present on those items.   To do this, set `itemController` to the name of a
+  controller (probably an `ObjectController`) that will wrap each individual item.
+
+  For example:
+
+  ```handlebars
+    {{#each post in controller}}
+      <li>{{title}} ({{titleLength}} characters)</li>
+    {{/each}}
+  ```
+
+  ```javascript
+  App.PostsController = Ember.ArrayController.extend({
+    itemController: 'post'
+  });
+
+  App.PostController = Ember.ObjectController.extend({
+    // the `title` property will be proxied to the underlying post.
+
+    titleLength: function() {
+      return this.get('title').length;
+    }.property('title')
+  });
+  ```
+
+  In some cases it is helpful to return a different `itemController` depending
+  on the particular item.  Subclasses can do this by overriding
+  `lookupItemController`.
+
+  For example:
+
+  ```javascript
+  App.MyArrayController = Ember.ArrayController.extend({
+    lookupItemController: function( object ) {
+      if (object.get('isSpecial')) {
+        return "special"; // use App.SpecialController
+      } else {
+        return "regular"; // use App.RegularController
+      }
+    }
+  });
+  ```
+
+  The itemController instances will have a `parentController` property set to
+  either the the `parentController` property of the `ArrayController`
+  or to the `ArrayController` instance itself.
+
+  @class ArrayController

+/**
+  `Ember.View` is the class in Ember responsible for encapsulating templates of
+  HTML content, combining templates with data to render as sections of a page's
+  DOM, and registering and responding to user-initiated events.
+
+  ## HTML Tag
+
+  The default HTML tag name used for a view's DOM representation is `div`. This
+  can be customized by setting the `tagName` property. The following view
+class:
+
+  ```javascript
+  ParagraphView = Ember.View.extend({
+    tagName: 'em'
+  });
+  ```
+
+  Would result in instances with the following HTML:
+
+  ```html
+  <em id="ember1" class="ember-view"></em>
+  ```
+
+  ## HTML `class` Attribute
+
+  The HTML `class` attribute of a view's tag can be set by providing a
+  `classNames` property that is set to an array of strings:
+
+  ```javascript
+  MyView = Ember.View.extend({
+    classNames: ['my-class', 'my-other-class']
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view my-class my-other-class"></div>
+  ```
+
+  `class` attribute values can also be set by providing a `classNameBindings`
+  property set to an array of properties names for the view. The return value
+  of these properties will be added as part of the value for the view's `class`
+  attribute. These properties can be computed properties:
+
+  ```javascript
+  MyView = Ember.View.extend({
+    classNameBindings: ['propertyA', 'propertyB'],
+    propertyA: 'from-a',
+    propertyB: function(){
+      if(someLogic){ return 'from-b'; }
+    }.property()
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view from-a from-b"></div>
+  ```
+
+  If the value of a class name binding returns a boolean the property name
+  itself will be used as the class name if the property is true. The class name
+  will not be added if the value is `false` or `undefined`.
+
+  ```javascript
+  MyView = Ember.View.extend({
+    classNameBindings: ['hovered'],
+    hovered: true
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view hovered"></div>
+  ```
+
+  When using boolean class name bindings you can supply a string value other
+  than the property name for use as the `class` HTML attribute by appending the
+  preferred value after a ":" character when defining the binding:
+
+  ```javascript
+  MyView = Ember.View.extend({
+    classNameBindings: ['awesome:so-very-cool'],
+    awesome: true
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view so-very-cool"></div>
+  ```
+
+  Boolean value class name bindings whose property names are in a
+  camelCase-style format will be converted to a dasherized format:
+
+  ```javascript
+  MyView = Ember.View.extend({
+    classNameBindings: ['isUrgent'],
+    isUrgent: true
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view is-urgent"></div>
+  ```
+
+  Class name bindings can also refer to object values that are found by
+  traversing a path relative to the view itself:
+
+  ```javascript
+  MyView = Ember.View.extend({
+    classNameBindings: ['messages.empty']
+    messages: Ember.Object.create({
+      empty: true
+    })
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view empty"></div>
+  ```
+
+  If you want to add a class name for a property which evaluates to true and
+  and a different class name if it evaluates to false, you can pass a binding
+  like this:
+
+  ```javascript
+  // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false
+  Ember.View.create({
+    classNameBindings: ['isEnabled:enabled:disabled']
+    isEnabled: true
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view enabled"></div>
+  ```
+
+  When isEnabled is `false`, the resulting HTML reprensentation looks like
+  this:
+
+  ```html
+  <div id="ember1" class="ember-view disabled"></div>
+  ```
+
+  This syntax offers the convenience to add a class if a property is `false`:
+
+  ```javascript
+  // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
+  Ember.View.create({
+    classNameBindings: ['isEnabled::disabled']
+    isEnabled: true
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view"></div>
+  ```
+
+  When the `isEnabled` property on the view is set to `false`, it will result
+  in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view disabled"></div>
+  ```
+
+  Updates to the the value of a class name binding will result in automatic
+  update of the  HTML `class` attribute in the view's rendered HTML
+  representation. If the value becomes `false` or `undefined` the class name
+  will be removed.
+
+  Both `classNames` and `classNameBindings` are concatenated properties. See
+  `Ember.Object` documentation for more information about concatenated
+  properties.
+
+  ## HTML Attributes
+
+  The HTML attribute section of a view's tag can be set by providing an
+  `attributeBindings` property set to an array of property names on the view.
+  The return value of these properties will be used as the value of the view's
+  HTML associated attribute:
+
+  ```javascript
+  AnchorView = Ember.View.extend({
+    tagName: 'a',
+    attributeBindings: ['href'],
+    href: 'http://google.com'
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <a id="ember1" class="ember-view" href="http://google.com"></a>
+  ```
+
+  If the return value of an `attributeBindings` monitored property is a boolean
+  the property will follow HTML's pattern of repeating the attribute's name as
+  its value:
+
+  ```javascript
+  MyTextInput = Ember.View.extend({
+    tagName: 'input',
+    attributeBindings: ['disabled'],
+    disabled: true
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <input id="ember1" class="ember-view" disabled="disabled" />
+  ```
+
+  `attributeBindings` can refer to computed properties:
+
+  ```javascript
+  MyTextInput = Ember.View.extend({
+    tagName: 'input',
+    attributeBindings: ['disabled'],
+    disabled: function(){
+      if (someLogic) {
+        return true;
+      } else {
+        return false;
+      }
+    }.property()
+  });
+  ```
+
+  Updates to the the property of an attribute binding will result in automatic
+  update of the  HTML attribute in the view's rendered HTML representation.
+
+  `attributeBindings` is a concatenated property. See `Ember.Object`
+  documentation for more information about concatenated properties.
+
+  ## Templates
+
+  The HTML contents of a view's rendered representation are determined by its
+  template. Templates can be any function that accepts an optional context
+  parameter and returns a string of HTML that will be inserted within the
+  view's tag. Most typically in Ember this function will be a compiled
+  `Ember.Handlebars` template.
+
+  ```javascript
+  AView = Ember.View.extend({
+    template: Ember.Handlebars.compile('I am the template')
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view">I am the template</div>
+  ```
+
+  Within an Ember application is more common to define a Handlebars templates as
+  part of a page:
+
+  ```html
+  <script type='text/x-handlebars' data-template-name='some-template'>
+    Hello
+  </script>
+  ```
+
+  And associate it by name using a view's `templateName` property:
+
+  ```javascript
+  AView = Ember.View.extend({
+    templateName: 'some-template'
+  });
+  ```
+
+  Using a value for `templateName` that does not have a Handlebars template
+  with a matching `data-template-name` attribute will throw an error.
+
+  Assigning a value to both `template` and `templateName` properties will throw
+  an error.
+
+  For views classes that may have a template later defined (e.g. as the block
+  portion of a `{{view}}` Handlebars helper call in another template or in
+  a subclass), you can provide a `defaultTemplate` property set to compiled
+  template function. If a template is not later provided for the view instance
+  the `defaultTemplate` value will be used:
+
+  ```javascript
+  AView = Ember.View.extend({
+    defaultTemplate: Ember.Handlebars.compile('I was the default'),
+    template: null,
+    templateName: null
+  });
+  ```
+
+  Will result in instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view">I was the default</div>
+  ```
+
+  If a `template` or `templateName` is provided it will take precedence over
+  `defaultTemplate`:
+
+  ```javascript
+  AView = Ember.View.extend({
+    defaultTemplate: Ember.Handlebars.compile('I was the default')
+  });
+
+  aView = AView.create({
+    template: Ember.Handlebars.compile('I was the template, not default')
+  });
+  ```
+
+  Will result in the following HTML representation when rendered:
+
+  ```html
+  <div id="ember1" class="ember-view">I was the template, not default</div>
+  ```
+
+  ## View Context
+
+  The default context of the compiled template is the view's controller:
+
+  ```javascript
+  AView = Ember.View.extend({
+    template: Ember.Handlebars.compile('Hello {{excitedGreeting}}')
+  });
+
+  aController = Ember.Object.create({
+    firstName: 'Barry',
+    excitedGreeting: function(){
+      return this.get("content.firstName") + "!!!"
+    }.property()
+  });
+
+  aView = AView.create({
+    controller: aController,
+  });
+  ```
+
+  Will result in an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view">Hello Barry!!!</div>
+  ```
+
+  A context can also be explicitly supplied through the view's `context`
+  property. If the view has neither `context` nor `controller` properties, the
+  `parentView`'s context will be used.
+
+  ## Layouts
+
+  Views can have a secondary template that wraps their main template. Like
+  primary templates, layouts can be any function that  accepts an optional
+  context parameter and returns a string of HTML that will be inserted inside
+  view's tag. Views whose HTML element is self closing (e.g. `<input />`)
+  cannot have a layout and this property will be ignored.
+
+  Most typically in Ember a layout will be a compiled `Ember.Handlebars`
+  template.
+
+  A view's layout can be set directly with the `layout` property or reference
+  an existing Handlebars template by name with the `layoutName` property.
+
+  A template used as a layout must contain a single use of the Handlebars
+  `{{yield}}` helper. The HTML contents of a view's rendered `template` will be
+  inserted at this location:
+
+  ```javascript
+  AViewWithLayout = Ember.View.extend({
+    layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>")
+    template: Ember.Handlebars.compile("I got wrapped"),
+  });
+  ```
+
+  Will result in view instances with an HTML representation of:
+
+  ```html
+  <div id="ember1" class="ember-view">
+    <div class="my-decorative-class">
+      I got wrapped
+    </div>
+  </div>
+  ```
+
+  See `Handlebars.helpers.yield` for more information.
+
+  ## Responding to Browser Events
+
+  Views can respond to user-initiated events in one of three ways: method
+  implementation, through an event manager, and through `{{action}}` helper use
+  in their template or layout.
+
+  ### Method Implementation
+
+  Views can respond to user-initiated events by implementing a method that
+  matches the event name. A `jQuery.Event` object will be passed as the
+  argument to this method.
+
+  ```javascript
+  AView = Ember.View.extend({
+    click: function(event){
+      // will be called when when an instance's
+      // rendered element is clicked
+    }
+  });
+  ```
+
+  ### Event Managers
+
+  Views can define an object as their `eventManager` property. This object can
+  then implement methods that match the desired event names. Matching events
+  that occur on the view's rendered HTML or the rendered HTML of any of its DOM
+  descendants will trigger this method. A `jQuery.Event` object will be passed
+  as the first argument to the method and an  `Ember.View` object as the
+  second. The `Ember.View` will be the view whose rendered HTML was interacted
+  with. This may be the view with the `eventManager` property or one of its
+  descendent views.
+
+  ```javascript
+  AView = Ember.View.extend({
+    eventManager: Ember.Object.create({
+      doubleClick: function(event, view){
+        // will be called when when an instance's
+        // rendered element or any rendering
+        // of this views's descendent
+        // elements is clicked
+      }
+    })
+  });
+  ```
+
+  An event defined for an event manager takes precedence over events of the
+  same name handled through methods on the view.
+
+  ```javascript
+  AView = Ember.View.extend({
+    mouseEnter: function(event){
+      // will never trigger.
+    },
+    eventManager: Ember.Object.create({
+      mouseEnter: function(event, view){
+        // takes presedence over AView#mouseEnter
+      }
+    })
+  });
+  ```
+
+  Similarly a view's event manager will take precedence for events of any views
+  rendered as a descendent. A method name that matches an event name will not
+  be called if the view instance was rendered inside the HTML representation of
+  a view that has an `eventManager` property defined that handles events of the
+  name. Events not handled by the event manager will still trigger method calls
+  on the descendent.
+
+  ```javascript
+  OuterView = Ember.View.extend({
+    template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"),
+    eventManager: Ember.Object.create({
+      mouseEnter: function(event, view){
+        // view might be instance of either
+        // OuterView or InnerView depending on
+        // where on the page the user interaction occured
+      }
+    })
+  });
+
+  InnerView = Ember.View.extend({
+    click: function(event){
+      // will be called if rendered inside
+      // an OuterView because OuterView's
+      // eventManager doesn't handle click events
+    },
+    mouseEnter: function(event){
+      // will never be called if rendered inside
+      // an OuterView.
+    }
+  });
+  ```
+
+  ### Handlebars `{{action}}` Helper
+
+  See `Handlebars.helpers.action`.
+
+  ### Event Names
+
+  All of the event handling approaches described above respond to the same set
+  of events. The names of the built-in events are listed below. (The hash of
+  built-in events exists in `Ember.EventDispatcher`.) Additional, custom events
+  can be registered by using `Ember.Application.customEvents`.
+
+  Touch events:
+
+  * `touchStart`
+  * `touchMove`
+  * `touchEnd`
+  * `touchCancel`
+
+  Keyboard events
+
+  * `keyDown`
+  * `keyUp`
+  * `keyPress`
+
+  Mouse events
+
+  * `mouseDown`
+  * `mouseUp`
+  * `contextMenu`
+  * `click`
+  * `doubleClick`
+  * `mouseMove`
+  * `focusIn`
+  * `focusOut`
+  * `mouseEnter`
+  * `mouseLeave`
+
+  Form events:
+
+  * `submit`
+  * `change`
+  * `focusIn`
+  * `focusOut`
+  * `input`
+
+  HTML5 drag and drop events:
+
+  * `dragStart`
+  * `drag`
+  * `dragEnter`
+  * `dragLeave`
+  * `drop`
+  * `dragEnd`
+
+  ## Handlebars `{{view}}` Helper
+
+  Other `Ember.View` instances can be included as part of a view's template by
+  using the `{{view}}` Handlebars helper. See `Handlebars.helpers.view` for
+  additional information.

+  A `ContainerView` is an `Ember.View` subclass that implements `Ember.MutableArray`
+  allowing programatic management of its child views.
+
+  ## Setting Initial Child Views
+
+  The initial array of child views can be set in one of two ways. You can
+  provide a `childViews` property at creation time that contains instance of
+  `Ember.View`:
+
+  ```javascript
+  aContainer = Ember.ContainerView.create({
+    childViews: [Ember.View.create(), Ember.View.create()]
+  });
+  ```
+
+  You can also provide a list of property names whose values are instances of
+  `Ember.View`:
+
+  ```javascript
+  aContainer = Ember.ContainerView.create({
+    childViews: ['aView', 'bView', 'cView'],
+    aView: Ember.View.create(),
+    bView: Ember.View.create(),
+    cView: Ember.View.create()
+  });
+  ```
+
+  The two strategies can be combined:
+
+  ```javascript
+  aContainer = Ember.ContainerView.create({
+    childViews: ['aView', Ember.View.create()],
+    aView: Ember.View.create()
+  });
+  ```
+
+  Each child view's rendering will be inserted into the container's rendered
+  HTML in the same order as its position in the `childViews` property.
+
+  ## Adding and Removing Child Views
+
+  The container view implements `Ember.MutableArray` allowing programatic management of its child views.
+
+  To remove a view, pass that view into a `removeObject` call on the container view.
+
+  Given an empty `<body>` the following code
+
+  ```javascript
+  aContainer = Ember.ContainerView.create({
+    classNames: ['the-container'],
+    childViews: ['aView', 'bView'],
+    aView: Ember.View.create({
+      template: Ember.Handlebars.compile("A")
+    }),
+    bView: Ember.View.create({
+      template: Ember.Handlebars.compile("B")
+    })
+  });
+
+  aContainer.appendTo('body');
+  ```
+
+  Results in the HTML
+
+  ```html
+  <div class="ember-view the-container">
+    <div class="ember-view">A</div>
+    <div class="ember-view">B</div>
+  </div>
+  ```
+
+  Removing a view
+
+  ```javascript
+  aContainer.toArray();  // [aContainer.aView, aContainer.bView]
+  aContainer.removeObject(aContainer.get('bView'));
+  aContainer.toArray();  // [aContainer.aView]
+  ```
+
+  Will result in the following HTML
+
+  ```html
+  <div class="ember-view the-container">
+    <div class="ember-view">A</div>
+  </div>
+  ```
+
+  Similarly, adding a child view is accomplished by adding `Ember.View` instances to the
+  container view.
+
+  Given an empty `<body>` the following code
+
+  ```javascript
+  aContainer = Ember.ContainerView.create({
+    classNames: ['the-container'],
+    childViews: ['aView', 'bView'],
+    aView: Ember.View.create({
+      template: Ember.Handlebars.compile("A")
+    }),
+    bView: Ember.View.create({
+      template: Ember.Handlebars.compile("B")
+    })
+  });
+
+  aContainer.appendTo('body');
+  ```
+
+  Results in the HTML
+
+  ```html
+  <div class="ember-view the-container">
+    <div class="ember-view">A</div>
+    <div class="ember-view">B</div>
+  </div>
+  ```
+
+  Adding a view
+
+  ```javascript
+  AnotherViewClass = Ember.View.extend({
+    template: Ember.Handlebars.compile("Another view")
+  });
+
+  aContainer.toArray();  // [aContainer.aView, aContainer.bView]
+  aContainer.pushObject(AnotherViewClass.create());
+  aContainer.toArray(); // [aContainer.aView, aContainer.bView, <AnotherViewClass instance>]
+  ```
+
+  Will result in the following HTML
+
+  ```html
+  <div class="ember-view the-container">
+    <div class="ember-view">A</div>
+    <div class="ember-view">B</div>
+    <div class="ember-view">Another view</div>
+  </div>
+  ```
+
+  ## Templates and Layout
+
+  A `template`, `templateName`, `defaultTemplate`, `layout`, `layoutName` or
+  `defaultLayout` property on a container view will not result in the template
+  or layout being rendered. The HTML contents of a `Ember.ContainerView`'s DOM
+  representation will only be the rendered HTML of its child views.
+
+  ## Binding a View to Display
+
+  If you would like to display a single view in your ContainerView, you can set
+  its `currentView` property. When the `currentView` property is set to a view
+  instance, it will be added to the ContainerView. If the `currentView` property
+  is later changed to a different view, the new view will replace the old view.
+  If `currentView` is set to `null`, the last `currentView` will be removed.
+
+  This functionality is useful for cases where you want to bind the display of
+  a ContainerView to a controller or state manager. For example, you can bind
+  the `currentView` of a container to a controller like this:
+
+  ```javascript
+  App.appController = Ember.Object.create({
+    view: Ember.View.create({
+      templateName: 'person_template'
+    })
+  });
+  ```
+
+  ```handlebars
+  {{view Ember.ContainerView currentViewBinding="App.appController.view"}}
+  ```

+  @class ContainerView
+  @namespace Ember
+  @extends Ember.View

+/**
+  `Ember.CollectionView` is an `Ember.View` descendent responsible for managing
+  a collection (an array or array-like object) by maintaining a child view object
+  and associated DOM representation for each item in the array and ensuring
+  that child views and their associated rendered HTML are updated when items in
+  the array are added, removed, or replaced.
+
+  ## Setting content
+
+  The managed collection of objects is referenced as the `Ember.CollectionView`
+  instance's `content` property.
+
+  ```javascript
+  someItemsView = Ember.CollectionView.create({
+    content: ['A', 'B','C']
+  })
+  ```
+
+  The view for each item in the collection will have its `content` property set
+  to the item.
+
+  ## Specifying itemViewClass
+
+  By default the view class for each item in the managed collection will be an
+  instance of `Ember.View`. You can supply a different class by setting the
+  `CollectionView`'s `itemViewClass` property.
+
+  Given an empty `<body>` and the following code:
+
+  ```javascript
+  someItemsView = Ember.CollectionView.create({
+    classNames: ['a-collection'],
+    content: ['A','B','C'],
+    itemViewClass: Ember.View.extend({
+      template: Ember.Handlebars.compile("the letter: {{view.content}}")
+    })
+  });
+
+  someItemsView.appendTo('body');
+  ```
+
+  Will result in the following HTML structure
+
+  ```html
+  <div class="ember-view a-collection">
+    <div class="ember-view">the letter: A</div>
+    <div class="ember-view">the letter: B</div>
+    <div class="ember-view">the letter: C</div>
+  </div>
+  ```
+
+  ## Automatic matching of parent/child tagNames
+
+  Setting the `tagName` property of a `CollectionView` to any of
+  "ul", "ol", "table", "thead", "tbody", "tfoot", "tr", or "select" will result
+  in the item views receiving an appropriately matched `tagName` property.
+
+  Given an empty `<body>` and the following code:
+
+  ```javascript
+  anUndorderedListView = Ember.CollectionView.create({
+    tagName: 'ul',
+    content: ['A','B','C'],
+    itemViewClass: Ember.View.extend({
+      template: Ember.Handlebars.compile("the letter: {{view.content}}")
+    })
+  });
+
+  anUndorderedListView.appendTo('body');
+  ```
+
+  Will result in the following HTML structure
+
+  ```html
+  <ul class="ember-view a-collection">
+    <li class="ember-view">the letter: A</li>
+    <li class="ember-view">the letter: B</li>
+    <li class="ember-view">the letter: C</li>
+  </ul>
+  ```
+
+  Additional `tagName` pairs can be provided by adding to
+  `Ember.CollectionView.CONTAINER_MAP `
+
+  ```javascript
+  Ember.CollectionView.CONTAINER_MAP['article'] = 'section'
+  ```
+
+  ## Programatic creation of child views
+
+  For cases where additional customization beyond the use of a single
+  `itemViewClass` or `tagName` matching is required CollectionView's
+  `createChildView` method can be overidden:
+
+  ```javascript
+  CustomCollectionView = Ember.CollectionView.extend({
+    createChildView: function(viewClass, attrs) {
+      if (attrs.content.kind == 'album') {
+        viewClass = App.AlbumView;
+      } else {
+        viewClass = App.SongView;
+      }
+      return this._super(viewClass, attrs);
+    }
+  });
+  ```
+
+  ## Empty View
+
+  You can provide an `Ember.View` subclass to the `Ember.CollectionView`
+  instance as its `emptyView` property. If the `content` property of a
+  `CollectionView` is set to `null` or an empty array, an instance of this view
+  will be the `CollectionView`s only child.
+
+  ```javascript
+  aListWithNothing = Ember.CollectionView.create({
+    classNames: ['nothing']
+    content: null,
+    emptyView: Ember.View.extend({
+      template: Ember.Handlebars.compile("The collection is empty")
+    })
+  });
+
+  aListWithNothing.appendTo('body');
+  ```
+
+  Will result in the following HTML structure
+
+  ```html
+  <div class="ember-view nothing">
+    <div class="ember-view">
+      The collection is empty
+    </div>
+  </div>
+  ```
+
+  ## Adding and Removing items
+
+  The `childViews` property of a `CollectionView` should not be directly
+  manipulated. Instead, add, remove, replace items from its `content` property.
+  This will trigger appropriate changes to its rendered HTML.
+
+  ## Use in templates via the `{{collection}}` `Ember.Handlebars` helper
+
+  `Ember.Handlebars` provides a helper specifically for adding
+  `CollectionView`s to templates. See `Ember.Handlebars.collection` for more
+  details

+  An `Ember.Component` is a view that is completely
+  isolated. Property access in its templates go
+  to the view object and actions are targeted at
+  the view object. There is no access to the
+  surrounding context or outer controller; all
+  contextual information is passed in.
+
+  The easiest way to create an `Ember.Component` is via
+  a template. If you name a template
+  `controls/my-foo`, you will be able to use
+  `{{my-foo}}` in other templates, which will make
+  an instance of the isolated control.
+
+  ```html
+  {{app-profile person=currentUser}}
+  ```
+
+  ```html
+  <!-- app-profile template -->
+  <h1>{{person.title}}</h1>
+  <img {{bindAttr src=person.avatar}}>
+  <p class='signature'>{{person.signature}}</p>
+  ```
+
+  You can also use `yield` inside a template to
+  include the **contents** of the custom tag:
+
+  ```html
+  {{#my-profile person=currentUser}}
+  <p>Admin mode</p>
+  {{/my-profile}}
+  ```
+
+  ```html
+  <!-- app-profile template -->
+
+  <h1>{{person.title}}</h1>
+  {{yield}} <!-- block contents -->
+  ```
+
+  If you want to customize the control, in order to
+  handle events or actions, you implement a subclass
+  of `Ember.Component` named after the name of the
+  control.
+
+  For example, you could implement the action
+  `hello` for the `app-profile` control:
+
+  ```js
+  App.AppProfileComponent = Ember.Component.extend({
+    hello: function(name) {
+      console.log("Hello", name)
+    }
+  });
+  ```
+
+  And then use it in the control's template:
+
+  ```html
+  <!-- app-profile template -->
+
+  <h1>{{person.title}}</h1>
+  {{yield}} <!-- block contents -->
+
+  <button {{action 'hello' person.name}}>
+    Say Hello to {{person.name}}
+  </button>
+  ```
+
+  Components must have a `-` in their name to avoid
+  conflicts with built-in controls that wrap HTML
+  elements. This is consistent with the same
+  requirement in web components.

+`Ember.ViewTargetActionSupport` is a mixin that can be included in a
+view class to add a `triggerAction` method with semantics similar to
+the Handlebars `{{action}}` helper. It provides intelligent defaults
+for the action's target: the view's controller; and the context that is
+sent with the action: the view's context.
+
+Note: In normal Ember usage, the `{{action}}` helper is usually the best
+choice. This mixin is most often useful when you are doing more complex
+event handling in custom View subclasses.
+
+For example:
+
+```javascript
+App.SaveButtonView = Ember.View.extend(Ember.ViewTargetActionSupport, {
+  action: 'save',
+  click: function(){
+    this.triggerAction(); // Sends the `save` action, along with the current context
+                          // to the current controller
+  }
+});
+```
+
+The `action` can be provided as properties of an optional object argument
+to `triggerAction` as well.
+
+```javascript
+App.SaveButtonView = Ember.View.extend(Ember.ViewTargetActionSupport, {
+  click: function(){
+    this.triggerAction({
+      action: 'save'
+    }); // Sends the `save` action, along with the current context
+        // to the current controller
+  }
+});

+/**
+  Register a bound handlebars helper. Bound helpers behave similarly to regular
+  handlebars helpers, with the added ability to re-render when the underlying data
+  changes.
+
+  ## Simple example
+
+  ```javascript
+  Ember.Handlebars.registerBoundHelper('capitalize', function(value) {
+    return value.toUpperCase();
+  });
+  ```
+
+  The above bound helper can be used inside of templates as follows:
+
+  ```handlebars
+  {{capitalize name}}
+  ```
+
+  In this case, when the `name` property of the template's context changes,
+  the rendered value of the helper will update to reflect this change.
+
+  ## Example with options
+
+  Like normal handlebars helpers, bound helpers have access to the options
+  passed into the helper call.
+
+  ```javascript
+  Ember.Handlebars.registerBoundHelper('repeat', function(value, options) {
+    var count = options.hash.count;
+    var a = [];
+    while(a.length < count){
+        a.push(value);
+    }
+    return a.join('');
+  });
+  ```
+
+  This helper could be used in a template as follows:
+
+  ```handlebars
+  {{repeat text count=3}}
+  ```
+
+  ## Example with bound options
+
+  Bound hash options are also supported. Example:
+
+  ```handlebars
+  {{repeat text countBinding="numRepeats"}}
+  ```
+
+  In this example, count will be bound to the value of
+  the `numRepeats` property on the context. If that property
+  changes, the helper will be re-rendered.
+
+  ## Example with extra dependencies
+
+  The `Ember.Handlebars.registerBoundHelper` method takes a variable length
+  third parameter which indicates extra dependencies on the passed in value.
+  This allows the handlebars helper to update when these dependencies change.
+
+  ```javascript
+  Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) {
+    return value.get('name').toUpperCase();
+  }, 'name');
+  ```
+
+  ## Example with multiple bound properties
+
+  `Ember.Handlebars.registerBoundHelper` supports binding to
+  multiple properties, e.g.:
+
+  ```javascript
+  Ember.Handlebars.registerBoundHelper('concatenate', function() {
+    var values = arguments[arguments.length - 1];
+    return values.join('||');
+  });
+  ```
+
+  Which allows for template syntax such as `{{concatenate prop1 prop2}}` or
+  `{{concatenate prop1 prop2 prop3}}`. If any of the properties change,
+  the helpr will re-render.  Note that dependency keys cannot be
+  using in conjunction with multi-property helpers, since it is ambiguous
+  which property the dependent keys would belong to.
+
+  ## Use with unbound helper
+
+  The `{{unbound}}` helper can be used with bound helper invocations
+  to render them in their unbound form, e.g.
+
+  ```handlebars
+  {{unbound capitalize name}}
+  ```
+
+  In this example, if the name property changes, the helper
+  will not re-render.
+
+  ## Use with blocks not supported
+
+  Bound helpers do not support use with Handlebars blocks or
+  the addition of child views of any kind.

+  `bindAttr` allows you to create a binding between DOM element attributes and

+
+  ```handlebars
+  <img {{bindAttr src="imageUrl" alt="imageTitle"}}>
+  ```
+
+  The above handlebars template will fill the `<img>`'s `src` attribute will
+  the value of the property referenced with `"imageUrl"` and its `alt`
+  attribute with the value of the property referenced with `"imageTitle"`.
+
+  If the rendering context of this template is the following object:
+
+  ```javascript
+  {
+    imageUrl: 'http://lolcats.info/haz-a-funny',
+    imageTitle: 'A humorous image of a cat'
+  }
+  ```
+
+  The resulting HTML output will be:
+
+  ```html
+  <img src="http://lolcats.info/haz-a-funny" alt="A humorous image of a cat">
+  ```
+
+  `bindAttr` cannot redeclare existing DOM element attributes. The use of `src`
+  in the following `bindAttr` example will be ignored and the hard coded value
+  of `src="/failwhale.gif"` will take precedence:
+
+  ```handlebars
+  <img src="/failwhale.gif" {{bindAttr src="imageUrl" alt="imageTitle"}}>
+  ```
+
+  ### `bindAttr` and the `class` attribute
+
+  `bindAttr` supports a special syntax for handling a number of cases unique
+  to the `class` DOM element attribute. The `class` attribute combines
+  multiple discreet values into a single attribute as a space-delimited
+  list of strings. Each string can be:
+
+  * a string return value of an object's property.
+  * a boolean return value of an object's property
+  * a hard-coded value
+
+  A string return value works identically to other uses of `bindAttr`. The
+  return value of the property will become the value of the attribute. For
+  example, the following view and template:
+
+  ```javascript
+    AView = Ember.View.extend({
+      someProperty: function(){
+        return "aValue";
+      }.property()
+    })
+  ```
+
+  ```handlebars
+  <img {{bindAttr class="view.someProperty}}>
+  ```
+
+  Result in the following rendered output:
+
+  ```html
+  <img class="aValue">
+  ```
+
+  A boolean return value will insert a specified class name if the property
+  returns `true` and remove the class name if the property returns `false`.
+
+  A class name is provided via the syntax
+  `somePropertyName:class-name-if-true`.
+
+  ```javascript
+  AView = Ember.View.extend({
+    someBool: true
+  })
+  ```
+
+  ```handlebars
+  <img {{bindAttr class="view.someBool:class-name-if-true"}}>
+  ```
+
+  Result in the following rendered output:
+
+  ```html
+  <img class="class-name-if-true">
+  ```
+
+  An additional section of the binding can be provided if you want to
+  replace the existing class instead of removing it when the boolean
+  value changes:
+
+  ```handlebars
+  <img {{bindAttr class="view.someBool:class-name-if-true:class-name-if-false"}}>
+  ```
+
+  A hard-coded value can be used by prepending `:` to the desired
+  class name: `:class-name-to-always-apply`.
+
+  ```handlebars
+  <img {{bindAttr class=":class-name-to-always-apply"}}>
+  ```
+
+  Results in the following rendered output:
+
+  ```html
+  <img class="class-name-to-always-apply">
+  ```
+
+  All three strategies - string return value, boolean return value, and
+  hard-coded value – can be combined in a single declaration:
+
+  ```handlebars
+  <img {{bindAttr class=":class-name-to-always-apply view.someBool:class-name-if-true view.someProperty"}}>
+  ```

+  options to the `Ember.View`'s `create` method and using the supplied block as
+  the view's own template.
+
+  An empty `<body>` and the following template:
+
+  ```handlebars
+  A span:
+  {{#view tagName="span"}}
+    hello.
+  {{/view}}
+  ```
+
+  Will result in HTML structure:
+
+  ```html
+  <body>
+    <!-- Note: the handlebars template script
+         also results in a rendered Ember.View
+         which is the outer <div> here -->
+
+    <div class="ember-view">
+      A span:
+      <span id="ember1" class="ember-view">
+        Hello.
+      </span>
+    </div>
+  </body>
+  ```
+
+  ### `parentView` setting
+
+  The `parentView` property of the new `Ember.View` instance created through
+  `{{view}}` will be set to the `Ember.View` instance of the template where
+  `{{view}}` was called.
+
+  ```javascript
+  aView = Ember.View.create({
+    template: Ember.Handlebars.compile("{{#view}} my parent: {{parentView.elementId}} {{/view}}")
+  });
+
+  aView.appendTo('body');
+  ```
+
+  Will result in HTML structure:
+
+  ```html
+  <div id="ember1" class="ember-view">
+    <div id="ember2" class="ember-view">
+      my parent: ember1
+    </div>
+  </div>
+  ```
+
+  ### Setting CSS id and class attributes
+
+  The HTML `id` attribute can be set on the `{{view}}`'s resulting element with
+  the `id` option. This option will _not_ be passed to `Ember.View.create`.
+
+  ```handlebars
+  {{#view tagName="span" id="a-custom-id"}}
+    hello.
+  {{/view}}
+  ```
+
+  Results in the following HTML structure:
+
+  ```html
+  <div class="ember-view">
+    <span id="a-custom-id" class="ember-view">
+      hello.
+    </span>
+  </div>
+  ```
+
+  The HTML `class` attribute can be set on the `{{view}}`'s resulting element
+  with the `class` or `classNameBindings` options. The `class` option will
+  directly set the CSS `class` attribute and will not be passed to
+  `Ember.View.create`. `classNameBindings` will be passed to `create` and use
+  `Ember.View`'s class name binding functionality:
+
+  ```handlebars
+  {{#view tagName="span" class="a-custom-class"}}
+    hello.
+  {{/view}}
+  ```
+
+  Results in the following HTML structure:
+
+  ```html
+  <div class="ember-view">
+    <span id="ember2" class="ember-view a-custom-class">
+      hello.
+    </span>
+  </div>
+  ```
+
+  ### Supplying a different view class
+
+  `{{view}}` can take an optional first argument before its supplied options to
+  specify a path to a custom view class.
+
+  ```handlebars
+  {{#view "MyApp.CustomView"}}
+    hello.
+  {{/view}}
+  ```
+
+  The first argument can also be a relative path accessible from the current
+  context.
+
+  ```javascript
+  MyApp = Ember.Application.create({});
+  MyApp.OuterView = Ember.View.extend({
+    innerViewClass: Ember.View.extend({
+      classNames: ['a-custom-view-class-as-property']
+    }),
+    template: Ember.Handlebars.compile('{{#view "view.innerViewClass"}} hi {{/view}}')
+  });
+
+  MyApp.OuterView.create().appendTo('body');
+  ```
+
+  Will result in the following HTML:
+
+  ```html
+  <div id="ember1" class="ember-view">
+    <div id="ember2" class="ember-view a-custom-view-class-as-property">
+      hi
+    </div>
+  </div>
+  ```
+
+  ### Blockless use
+
+  If you supply a custom `Ember.View` subclass that specifies its own template
+  or provide a `templateName` option to `{{view}}` it can be used without
+  supplying a block. Attempts to use both a `templateName` option and supply a
+  block will throw an error.
+
+  ```handlebars
+  {{view "MyApp.ViewWithATemplateDefined"}}
+  ```
+
+  ### `viewName` property
+
+  You can supply a `viewName` option to `{{view}}`. The `Ember.View` instance
+  will be referenced as a property of its parent view by this name.
+
+  ```javascript
+  aView = Ember.View.create({
+    template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}')
+  });
+
+  aView.appendTo('body');
+  aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper
+  ```
+
+  @method view

+/**
+  `{{collection}}` is a `Ember.Handlebars` helper for adding instances of
+  `Ember.CollectionView` to a template. See `Ember.CollectionView` for
+  additional information on how a `CollectionView` functions.
+
+  `{{collection}}`'s primary use is as a block helper with a `contentBinding`
+  option pointing towards an `Ember.Array`-compatible object. An `Ember.View`
+  instance will be created for each item in its `content` property. Each view
+  will have its own `content` property set to the appropriate item in the
+  collection.
+
+  The provided block will be applied as the template for each item's view.
+
+  Given an empty `<body>` the following template:
+
+  ```handlebars
+  {{#collection contentBinding="App.items"}}
+    Hi {{view.content.name}}
+  {{/collection}}
+  ```
+
+  And the following application code
+
+  ```javascript
+  App = Ember.Application.create()
+  App.items = [
+    Ember.Object.create({name: 'Dave'}),
+    Ember.Object.create({name: 'Mary'}),
+    Ember.Object.create({name: 'Sara'})
+  ]
+  ```
+
+  Will result in the HTML structure below
+
+  ```html
+  <div class="ember-view">
+    <div class="ember-view">Hi Dave</div>
+    <div class="ember-view">Hi Mary</div>
+    <div class="ember-view">Hi Sara</div>
+  </div>
+  ```
+
+  ### Blockless Use
+
+  If you provide an `itemViewClass` option that has its own `template` you can
+  omit the block.
+
+  The following template:
+
+  ```handlebars
+  {{collection contentBinding="App.items" itemViewClass="App.AnItemView"}}
+  ```
+
+  And application code
+
+  ```javascript
+  App = Ember.Application.create();
+  App.items = [
+    Ember.Object.create({name: 'Dave'}),
+    Ember.Object.create({name: 'Mary'}),
+    Ember.Object.create({name: 'Sara'})
+  ];
+
+  App.AnItemView = Ember.View.extend({
+    template: Ember.Handlebars.compile("Greetings {{view.content.name}}")
+  });
+  ```
+
+  Will result in the HTML structure below
+
+  ```html
+  <div class="ember-view">
+    <div class="ember-view">Greetings Dave</div>
+    <div class="ember-view">Greetings Mary</div>
+    <div class="ember-view">Greetings Sara</div>
+  </div>
+  ```
+
+  ### Specifying a CollectionView subclass
+
+  By default the `{{collection}}` helper will create an instance of
+  `Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to
+  the helper by passing it as the first argument:
+
+  ```handlebars
+  {{#collection App.MyCustomCollectionClass contentBinding="App.items"}}
+    Hi {{view.content.name}}
+  {{/collection}}
+  ```
+
+  ### Forwarded `item.*`-named Options
+
+  As with the `{{view}}`, helper options passed to the `{{collection}}` will be
+  set on the resulting `Ember.CollectionView` as properties. Additionally,
+  options prefixed with `item` will be applied to the views rendered for each
+  item (note the camelcasing):
+
+  ```handlebars
+  {{#collection contentBinding="App.items"
+                itemTagName="p"
+                itemClassNames="greeting"}}
+    Howdy {{view.content.name}}
+  {{/collection}}
+  ```
+
+  Will result in the following HTML structure:
+
+  ```html
+  <div class="ember-view">
+    <p class="ember-view greeting">Howdy Dave</p>
+    <p class="ember-view greeting">Howdy Mary</p>
+    <p class="ember-view greeting">Howdy Sara</p>
+  </div>
+  ```

+/**
+  The `{{#each}}` helper loops over elements in a collection, rendering its
+  block once for each item. It is an extension of the base Handlebars `{{#each}}`
+  helper:
+
+  ```javascript
+  Developers = [{name: 'Yehuda'},{name: 'Tom'}, {name: 'Paul'}];
+  ```
+
+  ```handlebars
+  {{#each Developers}}
+    {{name}}
+  {{/each}}
+  ```
+
+  `{{each}}` supports an alternative syntax with element naming:
+
+  ```handlebars
+  {{#each person in Developers}}
+    {{person.name}}
+  {{/each}}
+  ```
+
+  When looping over objects that do not have properties, `{{this}}` can be used
+  to render the object:
+
+  ```javascript
+  DeveloperNames = ['Yehuda', 'Tom', 'Paul']
+  ```
+
+  ```handlebars
+  {{#each DeveloperNames}}
+    {{this}}
+  {{/each}}
+  ```
+  ### {{else}} condition
+  `{{#each}}` can have a matching `{{else}}`. The contents of this block will render
+  if the collection is empty.
+
+  ```
+  {{#each person in Developers}}
+    {{person.name}}
+  {{else}}
+    <p>Sorry, nobody is available for this task.</p>
+  {{/each}}
+  ```
+  ### Specifying a View class for items
+  If you provide an `itemViewClass` option that references a view class
+  with its own `template` you can omit the block.
+
+  The following template:
+
+  ```handlebars
+  {{#view App.MyView }}
+    {{each view.items itemViewClass="App.AnItemView"}}
+  {{/view}}
+  ```
+
+  And application code
+
+  ```javascript
+  App = Ember.Application.create({
+    MyView: Ember.View.extend({
+      items: [
+        Ember.Object.create({name: 'Dave'}),
+        Ember.Object.create({name: 'Mary'}),
+        Ember.Object.create({name: 'Sara'})
+      ]
+    })
+  });
+
+  App.AnItemView = Ember.View.extend({
+    template: Ember.Handlebars.compile("Greetings {{name}}")
+  });
+  ```
+
+  Will result in the HTML structure below
+
+  ```html
+  <div class="ember-view">
+    <div class="ember-view">Greetings Dave</div>
+    <div class="ember-view">Greetings Mary</div>
+    <div class="ember-view">Greetings Sara</div>
+  </div>
+  ```
+
+  ### Representing each item with a Controller.
+  By default the controller lookup within an `{{#each}}` block will be
+  the controller of the template where the `{{#each}}` was used. If each
+  item needs to be presented by a custom controller you can provide a
+  `itemController` option which references a controller by lookup name.
+  Each item in the loop will be wrapped in an instance of this controller
+  and the item itself will be set to the `content` property of that controller.
+
+  This is useful in cases where properties of model objects need transformation
+  or synthesis for display:
+
+  ```javascript
+  App.DeveloperController = Ember.ObjectController.extend({
+    isAvailableForHire: function(){
+      return !this.get('content.isEmployed') && this.get('content.isSeekingWork');
+    }.property('isEmployed', 'isSeekingWork')
+  })
+  ```
+
+  ```handlebars
+  {{#each person in developers itemController="developer"}}
+    {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}}
+  {{/each}}
+  ```
+
+  Each itemController will receive a reference to the current controller as
+  a `parentController` property.
+
+  @method each
+  @for Ember.Handlebars.helpers
+  @param [name] {String} name for item (used with `in`)

+
+/**
+  The `Ember.Select` view class renders a
+  [select](https://developer.mozilla.org/en/HTML/Element/select) HTML element,
+  allowing the user to choose from a list of options.
+
+  The text and `value` property of each `<option>` element within the
+  `<select>` element are populated from the objects in the `Element.Select`'s
+  `content` property. The underlying data object of the selected `<option>` is
+  stored in the `Element.Select`'s `value` property.
+
+  ### `content` as an array of Strings
+
+  The simplest version of an `Ember.Select` takes an array of strings as its
+  `content` property. The string will be used as both the `value` property and
+  the inner text of each `<option>` element inside the rendered `<select>`.
+
+  Example:
+
+  ```javascript
+  App.names = ["Yehuda", "Tom"];
+  ```
+
+  ```handlebars
+  {{view Ember.Select contentBinding="App.names"}}
+  ```
+
+  Would result in the following HTML:
+
+  ```html
+  <select class="ember-select">
+    <option value="Yehuda">Yehuda</option>
+    <option value="Tom">Tom</option>
+  </select>
+  ```
+
+  You can control which `<option>` is selected through the `Ember.Select`'s
+  `value` property directly or as a binding:
+
+  ```javascript
+  App.names = Ember.Object.create({
+    selected: 'Tom',
+    content: ["Yehuda", "Tom"]
+  });
+  ```
+
+  ```handlebars
+  {{view Ember.Select
+         contentBinding="App.names.content"
+         valueBinding="App.names.selected"
+  }}
+  ```
+
+  Would result in the following HTML with the `<option>` for 'Tom' selected:
+
+  ```html
+  <select class="ember-select">
+    <option value="Yehuda">Yehuda</option>
+    <option value="Tom" selected="selected">Tom</option>
+  </select>
+  ```
+
+  A user interacting with the rendered `<select>` to choose "Yehuda" would
+  update the value of `App.names.selected` to "Yehuda".
+
+  ### `content` as an Array of Objects
+
+  An `Ember.Select` can also take an array of JavaScript or Ember objects as
+  its `content` property.
+
+  When using objects you need to tell the `Ember.Select` which property should
+  be accessed on each object to supply the `value` attribute of the `<option>`
+  and which property should be used to supply the element text.
+
+  The `optionValuePath` option is used to specify the path on each object to
+  the desired property for the `value` attribute. The `optionLabelPath`
+  specifies the path on each object to the desired property for the
+  element's text. Both paths must reference each object itself as `content`:
+
+  ```javascript
+  App.programmers = [
+    Ember.Object.create({firstName: "Yehuda", id: 1}),
+    Ember.Object.create({firstName: "Tom",    id: 2})
+  ];
+  ```
+
+  ```handlebars
+  {{view Ember.Select
+         contentBinding="App.programmers"
+         optionValuePath="content.id"
+         optionLabelPath="content.firstName"}}
+  ```
+
+  Would result in the following HTML:
+
+  ```html
+  <select class="ember-select">
+    <option value="1">Yehuda</option>
+    <option value="2">Tom</option>
+  </select>
+  ```
+
+  The `value` attribute of the selected `<option>` within an `Ember.Select`
+  can be bound to a property on another object by providing a
+  `valueBinding` option:
+
+  ```javascript
+  App.programmers = [
+    Ember.Object.create({firstName: "Yehuda", id: 1}),
+    Ember.Object.create({firstName: "Tom",    id: 2})
+  ];
+
+  App.currentProgrammer = Ember.Object.create({
+    id: 2
+  });
+  ```
+
+  ```handlebars
+  {{view Ember.Select
+         contentBinding="App.programmers"
+         optionValuePath="content.id"
+         optionLabelPath="content.firstName"
+         valueBinding="App.currentProgrammer.id"}}
+  ```
+
+  Would result in the following HTML with a selected option:
+
+  ```html
+  <select class="ember-select">
+    <option value="1">Yehuda</option>
+    <option value="2" selected="selected">Tom</option>
+  </select>
+  ```
+
+  Interacting with the rendered element by selecting the first option
+  ('Yehuda') will update the `id` value of `App.currentProgrammer`
+  to match the `value` property of the newly selected `<option>`.
+
+  Alternatively, you can control selection through the underlying objects
+  used to render each object providing a `selectionBinding`. When the selected
+  `<option>` is changed, the property path provided to `selectionBinding`
+  will be updated to match the content object of the rendered `<option>`
+  element:
+
+  ```javascript
+  App.controller = Ember.Object.create({
+    selectedPerson: null,
+    content: [
+      Ember.Object.create({firstName: "Yehuda", id: 1}),
+      Ember.Object.create({firstName: "Tom",    id: 2})
+    ]
+  });
+  ```
+
+  ```handlebars
+  {{view Ember.Select
+         contentBinding="App.controller.content"
+         optionValuePath="content.id"
+         optionLabelPath="content.firstName"
+         selectionBinding="App.controller.selectedPerson"}}
+  ```
+
+  Would result in the following HTML with a selected option:
+
+  ```html
+  <select class="ember-select">
+    <option value="1">Yehuda</option>
+    <option value="2" selected="selected">Tom</option>
+  </select>
+  ```
+
+  Interacting with the rendered element by selecting the first option
+  ('Yehuda') will update the `selectedPerson` value of `App.controller`
+  to match the content object of the newly selected `<option>`. In this
+  case it is the first object in the `App.controller.content`
+
+  ### Supplying a Prompt
+
+  A `null` value for the `Ember.Select`'s `value` or `selection` property
+  results in there being no `<option>` with a `selected` attribute:
+
+  ```javascript
+  App.controller = Ember.Object.create({
+    selected: null,
+    content: [
+      "Yehuda",
+      "Tom"
+    ]
+  });
+  ```
+
+  ``` handlebars
+  {{view Ember.Select
+         contentBinding="App.controller.content"
+         valueBinding="App.controller.selected"
+  }}
+  ```
+
+  Would result in the following HTML:
+
+  ```html
+  <select class="ember-select">
+    <option value="Yehuda">Yehuda</option>
+    <option value="Tom">Tom</option>
+  </select>
+  ```
+
+  Although `App.controller.selected` is `null` and no `<option>`
+  has a `selected` attribute the rendered HTML will display the
+  first item as though it were selected. You can supply a string
+  value for the `Ember.Select` to display when there is no selection
+  with the `prompt` option:
+
+  ```javascript
+  App.controller = Ember.Object.create({
+    selected: null,
+    content: [
+      "Yehuda",
+      "Tom"
+    ]
+  });
+  ```
+
+  ```handlebars
+  {{view Ember.Select
+         contentBinding="App.controller.content"
+         valueBinding="App.controller.selected"
+         prompt="Please select a name"
+  }}
+  ```
+
+  Would result in the following HTML:
+
+  ```html
+  <select class="ember-select">
+    <option>Please select a name</option>
+    <option value="Yehuda">Yehuda</option>
+    <option value="Tom">Tom</option>
+  </select>
+  ```

+    action targets.
+
+    These functions will be invoked when a matching `{{action}}` is triggered
+    from within a template and the application's current route is this route.
+
+    Events can also be invoked from other parts of your application via `Route#send`
+    or `Controller#send`.
+
+    The context of the event will be this route.
+
+    ## Bubbling
+
+    By default, an event will stop bubbling once a handler defined
+    on the `events` hash handles it. To continue bubbling the event,
+    you must return `true` from the handler.
+
+    ## Built-in events
+
+    There are a few built-in events pertaining to transitions that you
+    can use to customize transition behavior: `willTransition` and
+    `error`.
+
+    ### `willTransition`
+
+    The `willTransition` event is fired at the beginning of any
+    attempted transition with a `Transition` object as the sole
+    argument. This event can be used for aborting, redirecting,
+    or decorating the transition from the currently active routes.
+
+    A good example is preventing navigation when a form is
+    half-filled out:
+
+    ```js
+    App.ContactFormRoute = Ember.Route.extend({
+      events: {
+        willTransition: function(transition) {
+          if (this.controller.get('userHasEnteredData')) {
+            this.controller.displayNavigationConfirm();
+            transition.abort();
+          }
+        }
+      }
+    });
+    ```
+
+    You can also redirect elsewhere by calling 
+    `this.transitionTo('elsewhere')` from within `willTransition`.
+    Note that `willTransition` will not be fired for the
+    redirecting `transitionTo`, since `willTransition` doesn't
+    fire when there is already a transition underway. If you want
+    subsequent `willTransition` events to fire for the redirecting
+    transition, you must first explicitly call
+    `transition.abort()`.
+
+    ### `error`
+
+    When attempting to transition into a route, any of the hooks
+    may throw an error, or return a promise that rejects, at which
+    point an `error` event will be fired on the partially-entered
+    routes, allowing for per-route error handling logic, or shared
+    error handling logic defined on a parent route. 
+    
+    Here is an example of an error handler that will be invoked
+    for rejected promises / thrown errors from the various hooks
+    on the route, as well as any unhandled errors from child
+    routes:
+
+    ```js
+    App.AdminRoute = Ember.Route.extend({
+      beforeModel: function() {
+        throw "bad things!";
+        // ...or, equivalently:
+        return Ember.RSVP.reject("bad things!");
+      },
+
+      events: {
+        error: function(error, transition) {
+          // Assuming we got here due to the error in `beforeModel`,
+          // we can expect that error === "bad things!",
+          // but a promise model rejecting would also 
+          // call this hook, as would any errors encountered
+          // in `afterModel`. 
+
+          // The `error` hook is also provided the failed
+          // `transition`, which can be stored and later
+          // `.retry()`d if desired.
+
+          this.transitionTo('login');
+        }
+      }
+    });
+    ```
+
+    `error` events that bubble up all the way to `ApplicationRoute` 
+    will fire a default error handler that logs the error. You can
+    specify your own global default error handler by overriding the 
+    `error` handler on `ApplicationRoute`:
+
+    ```js
+    App.ApplicationRoute = Ember.Route.extend({
+      events: {
+        error: function(error, transition) {
+          this.controllerFor('banner').displayError(error.message);
+        }
+      }
+    });

+
+    1) A decision can be made to redirect elsewhere without
+       needing to resolve the model first.
+    2) Any async operations need to occur first before the 
+       model is attempted to be resolved.
+
+    This hook is provided the current `transition` attempt
+    as a parameter, which can be used to `.abort()` the transition,
+    save it for a later `.retry()`, or retrieve values set
+    on it from a previous hook. You can also just call
+    `this.transitionTo` to another route to implicitly 
+    abort the `transition`. 
+
+    You can return a promise from this hook to pause the
+    transition until the promise resolves (or rejects). This could
+    be useful, for instance, for retrieving async code from 
+    the server that is required to enter a route. 
+
+    ```js
+    App.PostRoute = Ember.Route.extend({
+      beforeModel: function(transition) {
+        if (!App.Post) {
+          return Ember.$.getScript('/models/post.js');
+        }
+      }
+    });
+    ```
+
+    If `App.Post` doesn't exist in the above example, 
+    `beforeModel` will use jQuery's `getScript`, which
+    returns a promise that resolves after the server has
+    successfully retrieved and executed the code from the
+    server. Note that if an error were to occur, it would 
+    be passed to the `error` hook on `Ember.Route`, but 
+    it's also possible to handle errors specific to 
+    `beforeModel` right from within the hook (to distinguish
+    from the shared error handling behavior of the `error`
+    hook):
+
+    ```js
+    App.PostRoute = Ember.Route.extend({
+      beforeModel: function(transition) {
+        if (!App.Post) {
+          var self = this;

+
+            // Note that the above transitionTo will implicitly
+            // halt the transition. If you were to return
+            // nothing from this promise reject handler, 
+            // according to promise semantics, that would
+            // convert the reject into a resolve and the

+            // error so that it'd be handled by the `error` 
+            // hook, you would have to either

+            // or
+            throw e;
+          });

+
+  /**
+    The `{{linkTo}}` helper renders a link to the supplied
+    `routeName` passing an optionally supplied model to the
+    route as its `model` context of the route. The block
+    for `{{linkTo}}` becomes the innerHTML of the rendered
+    element:
+
+    ```handlebars
+    {{#linkTo photoGallery}}
+      Great Hamster Photos
+    {{/linkTo}}
+    ```
+
+    ```html
+    <a href="/hamster-photos">
+      Great Hamster Photos
+    </a>
+    ```
+
+    ### Supplying a tagName
+    By default `{{linkTo}}` renders an `<a>` element. This can
+    be overridden for a single use of `{{linkTo}}` by supplying
+    a `tagName` option:
+
+    ```handlebars
+    {{#linkTo photoGallery tagName="li"}}
+      Great Hamster Photos
+    {{/linkTo}}
+    ```
+
+    ```html
+    <li>
+      Great Hamster Photos
+    </li>
+    ```
+
+    To override this option for your entire application, see 
+    "Overriding Application-wide Defaults".
+
+    ### Handling `href`
+    `{{linkTo}}` will use your application's Router to
+    fill the element's `href` property with a url that
+    matches the path to the supplied `routeName` for your
+    routers's configured `Location` scheme, which defaults
+    to Ember.HashLocation.
+
+    ### Handling current route
+    `{{linkTo}}` will apply a CSS class name of 'active'
+    when the application's current route matches
+    the supplied routeName. For example, if the application's
+    current route is 'photoGallery.recent' the following
+    use of `{{linkTo}}`:
+
+    ```handlebars
+    {{#linkTo photoGallery.recent}}
+      Great Hamster Photos from the last week
+    {{/linkTo}}
+    ```
+
+    will result in
+
+    ```html
+    <a href="/hamster-photos/this-week" class="active">
+      Great Hamster Photos
+    </a>
+    ```
+
+    The CSS class name used for active classes can be customized
+    for a single use of `{{linkTo}}` by passing an `activeClass`
+    option:
+
+    ```handlebars
+    {{#linkTo photoGallery.recent activeClass="current-url"}}
+      Great Hamster Photos from the last week
+    {{/linkTo}}
+    ```
+
+    ```html
+    <a href="/hamster-photos/this-week" class="current-url">
+      Great Hamster Photos
+    </a>
+    ```
+
+    To override this option for your entire application, see 
+    "Overriding Application-wide Defaults".
+
+    ### Supplying a model
+    An optional model argument can be used for routes whose
+    paths contain dynamic segments. This argument will become
+    the model context of the linked route:
+
+    ```javascript
+    App.Router.map(function(){
+      this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
+    })
+    ```
+
+    ```handlebars
+    {{#linkTo photoGallery aPhoto}}
+      {{aPhoto.title}}
+    {{/linkTo}}
+    ```
+
+    ```html
+    <a href="/hamster-photos/42">
+      Tomster
+    </a>
+    ```
+
+    ### Supplying multiple models
+    For deep-linking to route paths that contain multiple
+    dynamic segments, multiple model arguments can be used.
+    As the router transitions through the route path, each
+    supplied model argument will become the context for the
+    route with the dynamic segments:
+
+    ```javascript
+    App.Router.map(function(){
+      this.resource("photoGallery", {path: "hamster-photos/:photo_id"}, function(){
+        this.route("comment", {path: "comments/:comment_id"});
+      });
+    });
+    ```
+    This argument will become the model context of the linked route:
+
+    ```handlebars
+    {{#linkTo photoGallery.comment aPhoto comment}}
+      {{comment.body}}
+    {{/linkTo}}
+    ```
+
+    ```html
+    <a href="/hamster-photos/42/comment/718">
+      A+++ would snuggle again.
+    </a>
+    ```
+
+    ### Overriding Application-wide Defaults
+    ``{{linkTo}}`` creates an instance of Ember.LinkView
+    for rendering. To override options for your entire
+    application, reopen Ember.LinkView and supply the
+    desired values:
+
+    ``` javascript
+    Ember.LinkView.reopen({
+      activeClass: "is-active",
+      tagName: 'li'
+    })
+    ```
+
+    It is also possible to override the default event in
+    this manner:
+
+    ``` javascript
+    Ember.LinkView.reopen({
+      eventName: 'customEventName'
+    });
+    ```
+
+    @method linkTo
+    @for Ember.Handlebars.helpers
+    @param {String} routeName
+    @param {Object} [context]*
+    @return {String} HTML string
+  */
+  Ember.Handlebars.registerHelper('linkTo', function(name) {
+    var options = [].slice.call(arguments, -1)[0];
+    var params = [].slice.call(arguments, 1, -1);
+
+    var hash = options.hash;
+
+    hash.namedRoute = name;
+    hash.currentWhen = hash.currentWhen || name;
+    hash.disabledBinding = hash.disabledWhen;
+
+    hash.parameters = {
+      context: this,
+      options: options,
+      params: params
+    };
+
+    return Ember.Handlebars.helpers.view.call(this, LinkView, options);
+  });

+

+    ```
+
+    By default, a template based on Ember's naming conventions will be rendered
+    into the `outlet` (e.g. `App.PostsRoute` will render the `posts` template).
+
+    You can render a different template by using the `render()` method in the
+    route's `renderTemplate` hook. The following will render the `favoritePost`
+    template into the `outlet`.
+
+    ``` javascript
+    App.PostsRoute = Ember.Route.extend({
+      renderTemplate: function() {
+        this.render('favoritePost');
+      }
+    });
+    ```
+
+    You can create custom named outlets for more control.
+
+    ``` handlebars
+    {{outlet favoritePost}}
+    {{outlet posts}}
+    ```
+
+    Then you can define what template is rendered into each outlet in your
+    route.
+
+
+    ``` javascript
+    App.PostsRoute = Ember.Route.extend({
+      renderTemplate: function() {
+        this.render('favoritePost', { outlet: 'favoritePost' });
+        this.render('posts', { outlet: 'posts' });
+      }
+    });
+    ```
+
+    You can specify the view class that the outlet uses to contain and manage the
+    templates rendered into it.
+
+    ``` handlebars
+    {{outlet viewClass=App.SectionContainer}}
+    ```
+
+    ``` javascript
+    App.SectionContainer = Ember.ContainerView.extend({

+    The `{{action}}` helper registers an HTML element within a template for DOM

+
+    If the view's controller does not implement the event, the event is sent
+    to the current route, and it bubbles up the route hierarchy from there.
+
+    User interaction with that element will invoke the supplied action name on
+    the appropriate target.
+
+    Given the following Handlebars template on the page
+
+    ```handlebars
+    <script type="text/x-handlebars" data-template-name='a-template'>
+      <div {{action anActionName}}>
+        click me
+      </div>
+    </script>
+    ```
+
+    And application code
+
+    ```javascript
+    AController = Ember.Controller.extend({
+      anActionName: function() {}
+    });
+
+    AView = Ember.View.extend({
+      controller: AController.create(),
+      templateName: 'a-template'
+    });
+
+    aView = AView.create();
+    aView.appendTo('body');
+    ```
+
+    Will result in the following rendered HTML
+
+    ```html
+    <div class="ember-view">
+      <div data-ember-action="1">
+        click me
+      </div>
+    </div>
+    ```
+
+    Clicking "click me" will trigger the `anActionName` method of the
+    `AController`. In this case, no additional parameters will be passed.
+
+    If you provide additional parameters to the helper:
+
+    ```handlebars
+    <button {{action 'edit' post}}>Edit</button>
+    ```
+
+    Those parameters will be passed along as arguments to the JavaScript
+    function implementing the action.
+
+    ### Event Propagation
+
+    Events triggered through the action helper will automatically have
+    `.preventDefault()` called on them. You do not need to do so in your event
+    handlers.
+
+    To also disable bubbling, pass `bubbles=false` to the helper:
+
+    ```handlebars
+    <button {{action 'edit' post bubbles=false}}>Edit</button>
+    ```
+
+    If you need the default handler to trigger you should either register your
+    own event handler, or use event methods on your view class. See `Ember.View`
+    'Responding to Browser Events' for more information.
+
+    ### Specifying DOM event type
+
+    By default the `{{action}}` helper registers for DOM `click` events. You can
+    supply an `on` option to the helper to specify a different DOM event name:
+
+    ```handlebars
+    <script type="text/x-handlebars" data-template-name='a-template'>
+      <div {{action anActionName on="doubleClick"}}>
+        click me
+      </div>
+    </script>
+    ```
+
+    See `Ember.View` 'Responding to Browser Events' for a list of
+    acceptable DOM event names.
+
+    NOTE: Because `{{action}}` depends on Ember's event dispatch system it will
+    only function if an `Ember.EventDispatcher` instance is available. An
+    `Ember.EventDispatcher` instance will be created when a new `Ember.Application`
+    is created. Having an instance of `Ember.Application` will satisfy this
+    requirement.
+
+    ### Specifying whitelisted modifier keys
+
+    By default the `{{action}}` helper will ignore click event with pressed modifier
+    keys. You can supply an `allowedKeys` option to specify which keys should not be ignored.
+
+    ```handlebars
+    <script type="text/x-handlebars" data-template-name='a-template'>
+      <div {{action anActionName allowedKeys="alt"}}>
+        click me
+      </div>
+    </script>
+    ```
+
+    This way the `{{action}}` will fire when clicking with the alt key pressed down.
+
+    ### Specifying a Target
+
+    There are several possible target objects for `{{action}}` helpers:
+
+    In a typical Ember application, where views are managed through use of the
+    `{{outlet}}` helper, actions will bubble to the current controller, then
+    to the current route, and then up the route hierarchy.
+
+    Alternatively, a `target` option can be provided to the helper to change
+    which object will receive the method call. This option must be a path
+    to an object, accessible in the current context:
+
+    ```handlebars
+    <script type="text/x-handlebars" data-template-name='a-template'>
+      <div {{action anActionName target="MyApplication.someObject"}}>
+        click me
+      </div>
+    </script>
+    ```
+
+    Clicking "click me" in the rendered HTML of the above template will trigger
+    the  `anActionName` method of the object at `MyApplication.someObject`.
+
+    If an action's target does not implement a method that matches the supplied
+    action name an error will be thrown.
+
+    ```handlebars
+    <script type="text/x-handlebars" data-template-name='a-template'>
+      <div {{action aMethodNameThatIsMissing}}>
+        click me
+      </div>
+    </script>
+    ```
+
+    With the following application code
+
+    ```javascript
+    AView = Ember.View.extend({
+      templateName; 'a-template',
+      // note: no method 'aMethodNameThatIsMissing'
+      anActionName: function(event) {}
+    });
+
+    aView = AView.create();
+    aView.appendTo('body');
+    ```
+
+    Will throw `Uncaught TypeError: Cannot call method 'call' of undefined` when
+    "click me" is clicked.
+
+    ### Additional Parameters
+
+    You may specify additional parameters to the `{{action}}` helper. These
+    parameters are passed along as the arguments to the JavaScript function
+    implementing the action.
+
+    ```handlebars
+    <script type="text/x-handlebars" data-template-name='a-template'>
+      {{#each person in people}}
+        <div {{action edit person}}>
+          click me
+        </div>
+      {{/each}}
+    </script>
+    ```
+
+    Clicking "click me" will trigger the `edit` method on the current view's
+    controller with the current person as a parameter.
+

+/**
+  The DefaultResolver defines the default lookup rules to resolve
+  container lookups before consulting the container for registered
+  items:
+
+  * templates are looked up on `Ember.TEMPLATES`
+  * other names are looked up on the application after converting
+    the name. For example, `controller:post` looks up
+    `App.PostController` by default.
+  * there are some nuances (see examples below)
+
+  ### How Resolving Works
+
+  The container calls this object's `resolve` method with the
+  `fullName` argument.
+
+  It first parses the fullName into an object using `parseName`.
+
+  Then it checks for the presence of a type-specific instance
+  method of the form `resolve[Type]` and calls it if it exists.
+  For example if it was resolving 'template:post', it would call
+  the `resolveTemplate` method.
+
+  Its last resort is to call the `resolveOther` method.
+
+  The methods of this object are designed to be easy to override
+  in a subclass. For example, you could enhance how a template
+  is resolved like so:
+
+  ```javascript
+  App = Ember.Application.create({
+    resolver: Ember.DefaultResolver.extend({
+      resolveTemplate: function(parsedName) {
+        var resolvedTemplate = this._super(parsedName);
+        if (resolvedTemplate) { return resolvedTemplate; }
+        return Ember.TEMPLATES['not_found'];
+      }
+    })
+  });
+  ```
+
+  Some examples of how names are resolved:
+
+  ```
+  'template:post' //=> Ember.TEMPLATES['post']
+  'template:posts/byline' //=> Ember.TEMPLATES['posts/byline']
+  'template:posts.byline' //=> Ember.TEMPLATES['posts/byline']

+/**
+  An instance of `Ember.Application` is the starting point for every Ember
+  application. It helps to instantiate, initialize and coordinate the many
+  objects that make up your app.
+
+  Each Ember app has one and only one `Ember.Application` object. In fact, the
+  very first thing you should do in your application is create the instance:
+
+  ```javascript
+  window.App = Ember.Application.create();
+  ```
+
+  Typically, the application object is the only global variable. All other
+  classes in your app should be properties on the `Ember.Application` instance,
+  which highlights its first role: a global namespace.
+
+  For example, if you define a view class, it might look like this:
+
+  ```javascript
+  App.MyView = Ember.View.extend();
+  ```
+
+  By default, calling `Ember.Application.create()` will automatically initialize
+  your application by calling the `Ember.Application.initialize()` method. If
+  you need to delay initialization, you can call your app's `deferReadiness()`
+  method. When you are ready for your app to be initialized, call its
+  `advanceReadiness()` method.
+
+  You can define a `ready` method on the `Ember.Application` instance, which
+  will be run by Ember when the application is initialized.
+
+  Because `Ember.Application` inherits from `Ember.Namespace`, any classes
+  you create will have useful string representations when calling `toString()`.
+  See the `Ember.Namespace` documentation for more information.
+
+  While you can think of your `Ember.Application` as a container that holds the
+  other classes in your application, there are several other responsibilities
+  going on under-the-hood that you may want to understand.
+
+  ### Event Delegation
+
+  Ember uses a technique called _event delegation_. This allows the framework
+  to set up a global, shared event listener instead of requiring each view to
+  do it manually. For example, instead of each view registering its own
+  `mousedown` listener on its associated element, Ember sets up a `mousedown`
+  listener on the `body`.
+
+  If a `mousedown` event occurs, Ember will look at the target of the event and
+  start walking up the DOM node tree, finding corresponding views and invoking
+  their `mouseDown` method as it goes.
+
+  `Ember.Application` has a number of default events that it listens for, as
+  well as a mapping from lowercase events to camel-cased view method names. For
+  example, the `keypress` event causes the `keyPress` method on the view to be
+  called, the `dblclick` event causes `doubleClick` to be called, and so on.
+
+  If there is a browser event that Ember does not listen for by default, you
+  can specify custom events and their corresponding view method names by
+  setting the application's `customEvents` property:
+
+  ```javascript
+  App = Ember.Application.create({
+    customEvents: {
+      // add support for the loadedmetadata media
+      // player event
+      'loadedmetadata': "loadedMetadata"
+    }
+  });
+  ```
+
+  By default, the application sets up these event listeners on the document
+  body. However, in cases where you are embedding an Ember application inside
+  an existing page, you may want it to set up the listeners on an element
+  inside the body.
+
+  For example, if only events inside a DOM element with the ID of `ember-app`
+  should be delegated, set your application's `rootElement` property:
+
+  ```javascript
+  window.App = Ember.Application.create({
+    rootElement: '#ember-app'
+  });
+  ```
+
+  The `rootElement` can be either a DOM element or a jQuery-compatible selector
+  string. Note that *views appended to the DOM outside the root element will
+  not receive events.* If you specify a custom root element, make sure you only
+  append views inside it!
+
+  To learn more about the advantages of event delegation and the Ember view
+  layer, and a list of the event listeners that are setup by default, visit the
+  [Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-delegation).
+
+  ### Initializers
+
+  Libraries on top of Ember can register additional initializers, like so:
+
+  ```javascript
+  Ember.Application.initializer({
+    name: "store",
+
+    initialize: function(container, application) {
+      container.register('store:main', application.Store);
+    }
+  });
+  ```
+
+  ### Routing
+
+  In addition to creating your application's router, `Ember.Application` is
+  also responsible for telling the router when to start routing. Transitions
+  between routes can be logged with the LOG_TRANSITIONS flag, and more
+  detailed intra-transition logging can be logged with
+  the LOG_TRANSITIONS_INTERNAL flag:
+
+  ```javascript
+  window.App = Ember.Application.create({
+    LOG_TRANSITIONS: true, // basic logging of successful transitions
+    LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps
+  });
+  ```
+
+  By default, the router will begin trying to translate the current URL into
+  application state once the browser emits the `DOMContentReady` event. If you
+  need to defer routing, you can call the application's `deferReadiness()`
+  method. Once routing can begin, call the `advanceReadiness()` method.
+
+  If there is any setup required before routing begins, you can implement a
+  `ready()` method on your app that will be invoked immediately before routing
+  begins.
+  ```
+
+  @class Application
+  @namespace Ember

+    application's `rootElement` property.

+
+    If you would like additional events to be delegated to your
+    views, set your `Ember.Application`'s `customEvents` property

+/**
+  StateManager is part of Ember's implementation of a finite state machine. A
+  StateManager instance manages a number of properties that are instances of
+  `Ember.State`,
+  tracks the current active state, and triggers callbacks when states have changed.
+
+  ## Defining States
+
+  The states of StateManager can be declared in one of two ways. First, you can
+  define a `states` property that contains all the states:
+
+  ```javascript
+  managerA = Ember.StateManager.create({
+    states: {
+      stateOne: Ember.State.create(),
+      stateTwo: Ember.State.create()
+    }
+  })
+
+  managerA.get('states')
+  // {
+  //   stateOne: Ember.State.create(),
+  //   stateTwo: Ember.State.create()
+  // }
+  ```
+
+  You can also add instances of `Ember.State` (or an `Ember.State` subclass)
+  directly as properties of a StateManager. These states will be collected into
+  the `states` property for you.
+
+  ```javascript
+  managerA = Ember.StateManager.create({
+    stateOne: Ember.State.create(),
+    stateTwo: Ember.State.create()
+  })
+
+  managerA.get('states')
+  // {
+  //   stateOne: Ember.State.create(),
+  //   stateTwo: Ember.State.create()
+  // }
+  ```
+
+  ## The Initial State
+
+  When created a StateManager instance will immediately enter into the state
+  defined as its `start` property or the state referenced by name in its
+  `initialState` property:
+
+  ```javascript
+  managerA = Ember.StateManager.create({
+    start: Ember.State.create({})
+  })
+
+  managerA.get('currentState.name') // 'start'
+
+  managerB = Ember.StateManager.create({
+    initialState: 'beginHere',
+    beginHere: Ember.State.create({})
+  })
+
+  managerB.get('currentState.name') // 'beginHere'
+  ```
+
+  Because it is a property you may also provide a computed function if you wish
+  to derive an `initialState` programmatically:
+
+  ```javascript
+  managerC = Ember.StateManager.create({
+    initialState: function(){
+      if (someLogic) {
+        return 'active';
+      } else {
+        return 'passive';
+      }
+    }.property(),
+    active: Ember.State.create({}),
+    passive: Ember.State.create({})
+  })
+  ```
+
+  ## Moving Between States
+
+  A StateManager can have any number of `Ember.State` objects as properties
+  and can have a single one of these states as its current state.
+
+  Calling `transitionTo` transitions between states:
+
+  ```javascript
+  robotManager = Ember.StateManager.create({
+    initialState: 'poweredDown',
+    poweredDown: Ember.State.create({}),
+    poweredUp: Ember.State.create({})
+  })
+
+  robotManager.get('currentState.name') // 'poweredDown'
+  robotManager.transitionTo('poweredUp')
+  robotManager.get('currentState.name') // 'poweredUp'
+  ```
+
+  Before transitioning into a new state the existing `currentState` will have
+  its `exit` method called with the StateManager instance as its first argument
+  and an object representing the transition as its second argument.
+
+  After transitioning into a new state the new `currentState` will have its
+  `enter` method called with the StateManager instance as its first argument
+  and an object representing the transition as its second argument.
+
+  ```javascript
+  robotManager = Ember.StateManager.create({
+    initialState: 'poweredDown',
+    poweredDown: Ember.State.create({
+      exit: function(stateManager){
+        console.log("exiting the poweredDown state")
+      }
+    }),
+    poweredUp: Ember.State.create({
+      enter: function(stateManager){
+        console.log("entering the poweredUp state. Destroy all humans.")
+      }
+    })
+  })
+
+  robotManager.get('currentState.name') // 'poweredDown'
+  robotManager.transitionTo('poweredUp')
+
+  // will log
+  // 'exiting the poweredDown state'
+  // 'entering the poweredUp state. Destroy all humans.'
+  ```
+
+  Once a StateManager is already in a state, subsequent attempts to enter that
+  state will not trigger enter or exit method calls. Attempts to transition
+  into a state that the manager does not have will result in no changes in the
+  StateManager's current state:
+
+  ```javascript
+  robotManager = Ember.StateManager.create({
+    initialState: 'poweredDown',
+    poweredDown: Ember.State.create({
+      exit: function(stateManager){
+        console.log("exiting the poweredDown state")
+      }
+    }),
+    poweredUp: Ember.State.create({
+      enter: function(stateManager){
+        console.log("entering the poweredUp state. Destroy all humans.")
+      }
+    })
+  })
+
+  robotManager.get('currentState.name') // 'poweredDown'
+  robotManager.transitionTo('poweredUp')
+  // will log
+  // 'exiting the poweredDown state'
+  // 'entering the poweredUp state. Destroy all humans.'
+  robotManager.transitionTo('poweredUp') // no logging, no state change
+
+  robotManager.transitionTo('someUnknownState') // silently fails
+  robotManager.get('currentState.name') // 'poweredUp'
+  ```
+
+  Each state property may itself contain properties that are instances of
+  `Ember.State`. The StateManager can transition to specific sub-states in a
+  series of transitionTo method calls or via a single transitionTo with the
+  full path to the specific state. The StateManager will also keep track of the
+  full path to its currentState
+
+  ```javascript
+  robotManager = Ember.StateManager.create({
+    initialState: 'poweredDown',
+    poweredDown: Ember.State.create({
+      charging: Ember.State.create(),
+      charged: Ember.State.create()
+    }),
+    poweredUp: Ember.State.create({
+      mobile: Ember.State.create(),
+      stationary: Ember.State.create()
+    })
+  })
+
+  robotManager.get('currentState.name') // 'poweredDown'
+
+  robotManager.transitionTo('poweredUp')
+  robotManager.get('currentState.name') // 'poweredUp'
+
+  robotManager.transitionTo('mobile')
+  robotManager.get('currentState.name') // 'mobile'
+
+  // transition via a state path
+  robotManager.transitionTo('poweredDown.charging')
+  robotManager.get('currentState.name') // 'charging'
+
+  robotManager.get('currentState.path') // 'poweredDown.charging'
+  ```
+
+  Enter transition methods will be called for each state and nested child state
+  in their hierarchical order. Exit methods will be called for each state and
+  its nested states in reverse hierarchical order.
+
+  Exit transitions for a parent state are not called when entering into one of
+  its child states, only when transitioning to a new section of possible states
+  in the hierarchy.
+
+  ```javascript
+  robotManager = Ember.StateManager.create({
+    initialState: 'poweredDown',
+    poweredDown: Ember.State.create({
+      enter: function(){},
+      exit: function(){
+        console.log("exited poweredDown state")
+      },
+      charging: Ember.State.create({
+        enter: function(){},
+        exit: function(){}
+      }),
+      charged: Ember.State.create({
+        enter: function(){
+          console.log("entered charged state")
+        },
+        exit: function(){
+          console.log("exited charged state")
+        }
+      })
+    }),
+    poweredUp: Ember.State.create({
+      enter: function(){
+        console.log("entered poweredUp state")
+      },
+      exit: function(){},
+      mobile: Ember.State.create({
+        enter: function(){
+          console.log("entered mobile state")
+        },
+        exit: function(){}
+      }),
+      stationary: Ember.State.create({
+        enter: function(){},
+        exit: function(){}
+      })
+    })
+  })
+
+
+  robotManager.get('currentState.path') // 'poweredDown'
+  robotManager.transitionTo('charged')
+  // logs 'entered charged state'
+  // but does *not* log  'exited poweredDown state'
+  robotManager.get('currentState.name') // 'charged
+
+  robotManager.transitionTo('poweredUp.mobile')
+  // logs
+  // 'exited charged state'
+  // 'exited poweredDown state'
+  // 'entered poweredUp state'
+  // 'entered mobile state'
+  ```
+
+  During development you can set a StateManager's `enableLogging` property to
+  `true` to receive console messages of state transitions.
+
+  ```javascript
+  robotManager = Ember.StateManager.create({
+    enableLogging: true
+  })
+  ```
+
+  ## Managing currentState with Actions
+
+  To control which transitions are possible for a given state, and
+  appropriately handle external events, the StateManager can receive and
+  route action messages to its states via the `send` method. Calling to
+  `send` with an action name will begin searching for a method with the same
+  name starting at the current state and moving up through the parent states
+  in a state hierarchy until an appropriate method is found or the StateManager
+  instance itself is reached.
+
+  If an appropriately named method is found it will be called with the state
+  manager as the first argument and an optional `context` object as the second
+  argument.
+
+  ```javascript
+  managerA = Ember.StateManager.create({
+    initialState: 'stateOne.substateOne.subsubstateOne',
+    stateOne: Ember.State.create({
+      substateOne: Ember.State.create({
+        anAction: function(manager, context){
+          console.log("an action was called")
+        },
+        subsubstateOne: Ember.State.create({})
+      })
+    })
+  })
+
+  managerA.get('currentState.name') // 'subsubstateOne'
+  managerA.send('anAction')
+  // 'stateOne.substateOne.subsubstateOne' has no anAction method
+  // so the 'anAction' method of 'stateOne.substateOne' is called
+  // and logs "an action was called"
+  // with managerA as the first argument
+  // and no second argument
+
+  someObject = {}
+  managerA.send('anAction', someObject)
+  // the 'anAction' method of 'stateOne.substateOne' is called again
+  // with managerA as the first argument and
+  // someObject as the second argument.
+  ```
+
+  If the StateManager attempts to send an action but does not find an appropriately named
+  method in the current state or while moving upwards through the state hierarchy, it will
+  repeat the process looking for a `unhandledEvent` method. If an `unhandledEvent` method is
+  found, it will be called with the original event name as the second argument. If an
+  `unhandledEvent` method is not found, the StateManager will throw a new Ember.Error.
+
+  ```javascript
+  managerB = Ember.StateManager.create({
+    initialState: 'stateOne.substateOne.subsubstateOne',
+    stateOne: Ember.State.create({
+      substateOne: Ember.State.create({
+        subsubstateOne: Ember.State.create({}),
+        unhandledEvent: function(manager, eventName, context) {
+          console.log("got an unhandledEvent with name " + eventName);
+        }
+      })
+    })
+  })
+
+  managerB.get('currentState.name') // 'subsubstateOne'
+  managerB.send('anAction')
+  // neither `stateOne.substateOne.subsubstateOne` nor any of it's
+  // parent states have a handler for `anAction`. `subsubstateOne`
+  // also does not have a `unhandledEvent` method, but its parent
+  // state, `substateOne`, does, and it gets fired. It will log
+  // "got an unhandledEvent with name anAction"
+  ```
+
+  Action detection only moves upwards through the state hierarchy from the current state.
+  It does not search in other portions of the hierarchy.
+
+  ```javascript
+  managerC = Ember.StateManager.create({
+    initialState: 'stateOne.substateOne.subsubstateOne',
+    stateOne: Ember.State.create({
+      substateOne: Ember.State.create({
+        subsubstateOne: Ember.State.create({})
+      })
+    }),
+    stateTwo: Ember.State.create({
+     anAction: function(manager, context){
+       // will not be called below because it is
+       // not a parent of the current state
+     }
+    })
+  })
+
+  managerC.get('currentState.name') // 'subsubstateOne'
+  managerC.send('anAction')
+  // Error: <Ember.StateManager:ember132> could not
+  // respond to event anAction in state stateOne.substateOne.subsubstateOne.
+  ```
+
+  Inside of an action method the given state should delegate `transitionTo` calls on its
+  StateManager.
+
+  ```javascript
+  robotManager = Ember.StateManager.create({
+    initialState: 'poweredDown.charging',
+    poweredDown: Ember.State.create({
+      charging: Ember.State.create({
+        chargeComplete: function(manager, context){
+          manager.transitionTo('charged')
+        }
+      }),
+      charged: Ember.State.create({
+        boot: function(manager, context){
+          manager.transitionTo('poweredUp')
+        }
+      })
+    }),
+    poweredUp: Ember.State.create({
+      beginExtermination: function(manager, context){
+        manager.transitionTo('rampaging')
+      },
+      rampaging: Ember.State.create()
+    })
+  })
+
+  robotManager.get('currentState.name') // 'charging'
+  robotManager.send('boot') // throws error, no boot action
+                            // in current hierarchy
+  robotManager.get('currentState.name') // remains 'charging'
+
+  robotManager.send('beginExtermination') // throws error, no beginExtermination
+                                          // action in current hierarchy
+  robotManager.get('currentState.name')   // remains 'charging'
+
+  robotManager.send('chargeComplete')
+  robotManager.get('currentState.name')   // 'charged'
+
+  robotManager.send('boot')
+  robotManager.get('currentState.name')   // 'poweredUp'
+
+  robotManager.send('beginExtermination', allHumans)
+  robotManager.get('currentState.name')   // 'rampaging'
+  ```
+
+  Transition actions can also be created using the `transitionTo` method of the `Ember.State` class. The
+  following example StateManagers are equivalent:
+
+  ```javascript
+  aManager = Ember.StateManager.create({
+    stateOne: Ember.State.create({
+      changeToStateTwo: Ember.State.transitionTo('stateTwo')
+    }),
+    stateTwo: Ember.State.create({})
+  })
+
+  bManager = Ember.StateManager.create({
+    stateOne: Ember.State.create({
+      changeToStateTwo: function(manager, context){
+        manager.transitionTo('stateTwo', context)
+      }
+    }),
+    stateTwo: Ember.State.create({})
+  })
+  ```
