Title: Get kata.combinations working.

I feel like it could benefit from some refactoring, but the basic algorithm seems to be working.

It would be nice to extract the logic that actually builds the combinations of a given size into a separate method, and indeed, to make it more generic, it really shouldn't be concatting 'em inline either. But hey, it's a start.
