/*******************************************************
 * This main program simulates a multi-game multiplayer
 * arcade gaming system. The program allows the player
 * to choose from four different games:
 *
 *  1) Simon
 *  2) Super Tic-Tac-Toe (first player, the red X)
 *  3) Pac-Man
 *  4) Rock, Paper, Scissors, Lizard, Spock
 * 
 * All games except Pac-Man communicate with another
 * gaming system via an XBee module to simulate
 * multiplayer. Pac-Man is multiplayer as well, but the
 * characters in the game are controlled using the three
 * tactile switches on one board.
