#Hiya guys,
#I'm Patrick McKenzie (patio11 on HN) and I'm doing this just out of joy of programming puzzles.
#Not really looking for a job at the moment.
#
#I've taken some liberty with standard Ruby programming conventions to make this one file without
#dependencies, for the ease of you actually running it.  It is the result of a very hack-in-progress
#sort of workflow.  A git repo showing my work in stages might be more interesting but, well,
#hard to submit that into the form.

// I use underscore.js below for utility but you can also just do a for loop.
