Tic-tac-Toe: Model Classes

[mcoombs32]

Implement model classes for tic-tac-toe, such as: player, board, game state, moves, etc

[brianmichaelmartin]

I created a branch for this, starting to work on it

[brianmichaelmartin]

I created the classes we will need although I have not fully implemented them yet. Board is pretty much finished, at least for tictactoe. Can place pieces, check what piece is where and check for game wins. Probably still need a reset method though

[brianmichaelmartin]

Basically done, just need to finish the hard AI and fix any bugs we find during unit testing

[brianmichaelmartin]

Im pretty sure this is done. I am going to close this issue. If we find issues later when its hooked up to the front end or during unit testing Ill reopen this

[brianmichaelmartin]

While unit testing Anthony found a glitch in the isGameOver method that will return a draw if the game fills the whole board. Should be a 5 minute fix. I'll do this when mike pushes his changes
