+/** 
+ * Displays a simple HUD window containing a progress indicator and two optional labels for short messages.
+ *
+ * This is a simple drop-in class for displaying a progress HUD view similar to Apple's private UIProgressHUD class.
+ * The MBProgressHUD window spans over the entire space given to it by the initWithFrame constructor and catches all
+ * user input on this region, thereby preventing the user operations on components below the view. The HUD itself is
+ * drawn centered as a rounded semi-transparent view which resizes depending on the user specified content.
+ *
+ * This view supports four modes of operation:
+ * - MBProgressHUDModeIndeterminate - shows a UIActivityIndicatorView
+ * - MBProgressHUDModeDeterminate - shows a custom round progress indicator
+ * - MBProgressHUDModeAnnularDeterminate - shows a custom annular progress indicator
+ * - MBProgressHUDModeCustomView - shows an arbitrary, user specified view (@see customView)
+ *
+ * All three modes can have optional labels assigned:
+ * - If the labelText property is set and non-empty then a label containing the provided content is placed below the
+ *   indicator view.
+ * - If also the detailsLabelText property is set then another label is placed below the first label.

+# MBProgressHUD [![Build Status](https://travis-ci.org/matej/MBProgressHUD.png)](https://travis-ci.org/matej/MBProgressHUD)
+
+MBProgressHUD is an iOS drop-in class that displays a translucent HUD with an indicator and/or labels while work is being done in a background thread. The HUD is meant as a replacement for the undocumented, private UIKit UIProgressHUD with some additional features.

+
+## Requirements
+
+MBProgressHUD works on any iOS version and is compatible with both ARC and non-ARC projects. It depends on the following Apple frameworks, which should already be included with most Xcode templates:
+
+* Foundation.framework
+* UIKit.framework
+* CoreGraphics.framework
+
+You will need LLVM 3.0 or later in order to build MBProgressHUD. 
+
+## Adding MBProgressHUD to your project
+
+### Cocoapods
+
+[CocoaPods](http://cocoapods.org) is the recommended way to add MBProgressHUD to your project.
+
+1. Add a pod entry for MBProgressHUD to your Podfile `pod 'MBProgressHUD', '~> 0.6'`
+2. Install the pod(s) by running `pod install`.
+3. Include MBProgressHUD wherever you need it with `#import "MBProgressHUD.h"`.
+
+### Source files
+
+Alternatively you can directly add the `MBProgressHUD.h` and `MBProgressHUD.m` source files to your project.
+
+1. Download the [latest code version](https://github.com/matej/MBProgressHUD/archive/master.zip) or add the repository as a git submodule to your git-tracked project. 
+2. Open your project in Xcode, then drag and drop `MBProgressHUD.h` and `MBProgressHUD.m` onto your project (use the "Product Navigator view"). Make sure to select Copy items when asked if you extracted the code archive outside of your project. 
+3. Include MBProgressHUD wherever you need it with `#import "MBProgressHUD.h"`.
+
+### Static library
+
+You can also add MBProgressHUD as a static library to your project or workspace. 
+
+1. Download the [latest code version](https://github.com/matej/MBProgressHUD/downloads) or add the repository as a git submodule to your git-tracked project. 
+2. Open your project in Xcode, then drag and drop `MBProgressHUD.xcodeproj` onto your project or workspace (use the "Product Navigator view"). 
+3. Select your target and go to the Build phases tab. In the Link Binary With Libraries section select the add button. On the sheet find and add `libMBProgressHUD.a`. You might also need to add `MBProgressHUD` to the Target Dependencies list. 
+4. Include MBProgressHUD wherever you need it with `#import <MBProgressHUD/MBProgressHUD.h>`.
+
+## Usage
+
+The main guideline you need to follow when dealing with MBProgressHUD while running long-running tasks is keeping the main thread work-free, so the UI can be updated promptly. The recommended way of using MBProgressHUD is therefore to set it up on the main thread and then spinning the task, that you want to perform, off onto a new thread. 
+
+```objective-c
+[MBProgressHUD showHUDAddedTo:self.view animated:YES];
+dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_LOW, 0), ^{
+	// Do something...
+	dispatch_async(dispatch_get_main_queue(), ^{
+		[MBProgressHUD hideHUDForView:self.view animated:YES];
+	});
+});
+```
+
+If you need to configure the HUD you can do this by using the MBProgressHUD reference that showHUDAddedTo:animated: returns. 
+
+```objective-c
+MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
+hud.mode = MBProgressHUDModeAnnularDeterminate;
+hud.labelText = @"Loading";
+[self doSomethingInBackgroundWithProgressCallback:^(float progress) {
+	hud.progress = progress;
+} completionCallback:^{
+	[hud hide:YES];
+}];
+```
+
+UI updates should always be done on the main thread. Some MBProgressHUD setters are however considered "thread safe" and can be called from background threads. Those also include `setMode:`, `setCustomView:`, `setLabelText:`, `setLabelFont:`, `setDetailsLabelText:`, `setDetailsLabelFont:` and `setProgress:`.
+
+If you need to run your long-running task in the main thread, you should perform it with a slight delay, so UIKit will have enough time to update the UI (i.e., draw the HUD) before you block the main thread with your task.
+
+```objective-c
+[MBProgressHUD showHUDAddedTo:self.view animated:YES];
+dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, 0.01 * NSEC_PER_SEC);
+dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
+	// Do something...
+	[MBProgressHUD hideHUDForView:self.view animated:YES];
+});
+```
+
+You should be aware that any HUD updates issued inside the above block won't be displayed until the block completes.
+
+For more examples, including how to use MBProgressHUD with asynchronous operations such as NSURLConnection, take a look at the bundled demo project. Extensive API documentation is provided in the header file (MBProgressHUD.h).
