Code repository on github

I uploaded my AI script code files to github so you can view the complete code instead of relying only on the videos.  I'm doing this because sometimes it is easier to look around in the code when you are learning.  I consolidated all of the functions and event handlers for an AI into one file, but I couldn't do that for the AI variables--sorry.  So if you are following along in the code and see a reference preceded with "this" and you can't figure out where it is coming from, that's why.  I committed the code but it hasn't shown up on github so hopefully I am doing things right.
