// ## JAVANOID GAME CLASS ######################################
// This is the most important class of javanoid : It creates and deletes
// all the geme objects, manages their lives ans collisions, and traducts
// on the game both the user and game events (user moves, bullets, pills
// & balls throws, next level, ...). It's also the player during demo mode.
