Modify the behavior of the template to implement a 2 player tic-tac-toe game. When player1 clicks a block, it turns yellow. When player2 clicks a block, it turns red. If a line of 3 blocks of either team is detected, the blocks of the line turn white and an appropriate message is displayed to the debug console. (either Player 2 wins or Player 1 wins);
