This purpose of this Tetris demo is to demostrate three things:
1) Structure of a game
	We have a game loop, a clock, an update method, and a draw method
	*) The clock calculates the number of seconds since the last loop.
		This allows us to move the game at a constant pace even if the CPU fluctuates.
	*) The update method does the logic of the game, including collision checks, random character generation, etc.
		The update method delegates the task, so each object is responsible for updating itself
	*) The draw method does the rendering of stuff to screen, and just like the update method, each object draws itself
