     27  * This is an implementation of the classic Game "Snake", in which you control a
     28  * serpent roaming around the garden looking for apples. Be careful, though,
     29  * because when you catch one, not only will you become longer, but you'll move
     30  * faster. Running into yourself or the walls will end the game.
