 *The Engine class (CEngine) can take in a board and turn it into a game map.
 *The Engine class then creates another grid which will below the game map
 *	that holds the nodes for the Intelligence class (CIntelligence).
 *The Node classes hold the data for where a ghost can move and are used to 
 *	send ghosts after the player.  If pacman is between Node A and Node B and
 *	a ghost finds itself in Node A, it will turn and head in the direction of
 *	Node B.  These Intelligence specifics are handled in the
