My initial changes and proposal on folder organization

Hey Nick, I've added my animation system to the project and added a little demo as well that animates a little megaman in the corner.

I'm following the PEP8 style guide and I think I've got it mostly in compliance. To be consistent with our style I've converted tabs to spaces for 2 space indention.

You can look over the code for suggestions and concerns. This is just a quick write up and isn't fully tested.

You can run the demo with python app/test.py
