Problem 36 - Done in Whitespace

As my last post described, Whitespace is a pretty reasonable language, who needs characters other than space, tab, and newline, anyway? Not me certainly! I below is my solution to Problem 36 in Whitespace...as well as a link that shows how I actually wrote this: essentially I described every action in pseudo code so I knew exactly what each section of whitespace was doing...if it wasn't for all those copious comments, there would be no way that I would have every finished. Also, it is worth noting that I configured vim to let me see $ for newline, ^I for indent, and ~ for space...were it not for that help in visualization, things would have been just a bit harder.
