feature(ngRepeat): add ruby style ranges

[Wildhoney]

Would it be useful to support ranges in the ng-repeat directive? For example, I'm implementing pagination, and simply want an incremental array from 1 to the amount of pages. For that I'm doing a simple for loop to populate an array which I loop through the traditional way. However, by supporting ranges we could eradicate that boilerplate code.

We could support the Ruby syntax, and support both double-period (..) and triple-period (...):

ng-repeat="index in [1...pages.length]"

Alternatively of course I could just create an abstract method for my array fill. Although I'm confident pagination won't be anywhere close to the only scenario where a range in the ngRepeat directive would be desirable.
