 * A GamePanel is meant to serve as the ultimate containing panel
 * to display the full game. When the GameDriver is first run, a GamePanel
 * is constructed with a title label and MainMenuPanel. As the game is played, 
 * any inner panels (LevelPanel, MainMenuPanel, InstructionsPanel) may 
 * simultaneously add new panels and remove themselves from their master 
 * GamePanel (to produce the illusion of "switching screens" to a new panel).
