/* 
 * Description	
 *	class to handle a square on the noughts-and-crosses grid.
 * Each square is numbered (0-8) and this number is used to identify the square.
 * If a square is unoccupied, a click places a cross in the square and the 
 * computer's response is found - see JButtonSquareActionPerformed().
 * Otherwise, code is mainly concerned with the square's state
 *
