[Feature] Allow ng-repeat or create similar function to take number inputs

[RikuKat]

ng-repeat is an extremely convenient directive, but I have found myself often wanting to use it in place of a for loop over integers, not just collections. For example, a form with user controlled number of input rows. While it is fairly trivial to create an array using the user input, I believe it would be worthwhile to expand ng-repeat or create another direction to take "1 in 100" instead of "1 in [0, 1, 2..., 99]".

+1 if it can be coded without too much overhead
It is a bit of syntactic sugar but I've found in a need of sth like this quite often.

May need some more discussions on this. Current behavior:

• If it's <li ng-repeat="number in n"> and $scope.n = -1, and we have $scope.click = function() { $scope.n++; }, you need to click twice before any <li> will be showing up. I think this is expected behavior but welcome any input.
• Currently the array is being constructed from scratch every time which I think has further room for improvement.

It seems to make better sense to implement a range notation rather than using a plain integer, as suggested in #3861.
