Starting at index 0, for an element n at index i,
you are allowed to jump at most n indexes ahead.

Given a list of numbers, find the minimum number of jumps to reach the end of
the list.

Example:

Input: [3, 2, 5, 1, 1, 9, 3, 4]
Output: 2

Explanation:

The minimum number of jumps to get to the end of the list is 2:
   3 -> 5 -> 4

Here's a starting point:

```python
def jumpToEnd(nums):
  # Fill this in.
print jumpToEnd([3, 2, 5, 1, 1, 9, 3, 4])
# 2
