I've been teaching a class (http://apprenticeworks.us http://apprenticeworks.us) based on the same original repo it seems like you found. I made a lot of the same changes as you as well. I ended up abstracting a lot of the "optimization" type code (the sectors for example) and changed the way the state of the player is kept to support multiple players in the future. Not sure if you'd be interested, but I have some content I'd be happy to add for background type information (i.e. degrees of freedom, calculating movement, frames of reference, etc). Might make a good starting point for contributors but not sure if that's the direction you see your documentation taking.
