Finding combinations of sets is very useful for several business logics that are suited to be solved with functional programming (distributed payload, weight balance...).

Useful feature?

Not useful enough to merit inclusion in core Underscore, but a great idea for an _.mixin function.

Hey @rafaelbandeira3 could you be a bit more specific? What exactly are you looking for as the inputs and outputs for a _.subsets function?

I wonder if it wouldn't be better to build more complicated combinatoric functions should into a library that depends on underscore rather than building it into underscore itself.
