Title: _.groupsOf

Needed something like this earlier today and was almost sure I would have found it in underscore. Super surprised when I didn't. Take it or leave it.

Includes tests and update to index.html for documentation. Ran `rake doc`, but changes produced seemed too big to be from just me, didn't spend much time looking at the diff though; backed them out, regardless.
