firstNonRepeating

	package main

	import "container/heap"

	// Mind that this is slower than doing one pass to count occurances of each letter then a second pass to get the first non repeating letter
	// This one does something else though, it will take the first least repeated letter. So, with any permutation of "aaaabbbcc" it would yield "c"
