Subject: [PATCH] TestXBoardProtocol hasn't changed much. Now it is in a
 package called test.

NEW FILE: TestMoves -> purpose is to test the Move class

NEW FILE: Move -> this is a first implementation of a simple class that
				  reads a string and converts it to a move or the opposite.

NEW FILE: BitBoard -> this class really doesn't do anything yet.
					  It only has definition of 14 bitboards but they are not
					  created yet.
