The great code cleanup!

Okay, so in my videos I keep saying that I will clean up the code and add some documentation.  As I have been working on some of the more complex features of the game, I realized that I needed to do the clean up now.  Last night I got through most of the code and got things straightened out and as a result I have also decided to publish the code so that people can take a look at it directly rather than just through video.  I'm working out the details, but the source should be up soon!
