/*
	Question 1: Clean the room function: given an input of [1,2,4,591,392,391,2,5,10,2,1,1,1,20,20], 
	make a function that organizes these into individual array that is ordered. 
	For example answer(ArrayFromAbove) should return: [[1,1,1,1],[2,2,2], 4,5,10,[20,20], 391, 392,591]. 
	Bonus: Make it so it organizes strings differently from number types. i.e. [1, "2", "3", 2] should return [[1,2], ["2", "3"]]
