  It could probably use some minor cleanup, documentation and 
proper unittests and constraints, moving to unsigned size_t; If 
front is used more than once than there's inefficiency with 
memory and remaking the array it builds (among other things). 
Could even make an opIndex for creating specific iterations of 
the results.

  But for it's simplicity I hope it does what you need. It really 
wasn't that hard to make.
