Combinatorics permutatons and product in javascript using lodash.js (like python's itertools)

	/**
	* Lodash mixins for combinatorics
	* Inspired by python itertools: https://docs.python.org/2.7/library/itertools.html
	*
	* Usage:
	* permutations([0,1,2],2) // [[0,1],[0,2],[1,0],[1,2],[2,0],[2,1]]
	* combinations([0,1,2],2) // [[0,1],[0,2],[1,2]]
	* combinations_with_replacement([0,1,2],2)// [[0,0],[0,1],[0,2],[1,1],[1,2],[2,2]]
	* product([0,1,2],[0,1,2]) // [[0,0],[0,1],[0,2],[1,0],[1,1],[1,2],[2,0],[2,1],[2,2]]
