Added some other executable projects for homework assignments.
Also added file Directories and path iteration.
Added Game library, GameState, Space, and Node classes.
Lots of architecture. Entites, Components, and Groups are all GameState Nodes.
Made a Transform, and did nothing with it.
Still need to implement a lot of the cloning and copying.
Once this is fully implemented, Controllers.
Added some model files for the OBJ viewer. Did a bunch of other stuff, but I forget.
