This commit consolidates the BoardChecker and BoardManager into one class: the BoadManager. It also makes the MakeMove method from the Player Abstract class require a multidimensional character array instead of an X and Y coordinate. The HumanPlayer's definition for MakeMove returns null, while the ComputerPlayer's definition for MakeMove currently returns a randomly generated CreatedMove of all valid moves which can be made. The ComputerAI and ComputerAITest classes have been deleted, as have some other tests made obsolete or redundant as a result of these changes.
