- Reorganized packages so that the computer agents are inside the model package.

- Added support for the player model inside Referee.java; high scores should now persist over a single execution of the program.
- Refactored PlayerModel.java to support game logging. All games are now logged so that we can track overall progress.
- Added scaffolding to allow saving and importing of PlayerModel.java. It is not yet functional, but it will be with two function implementations and then the appropriate calls.
