Create diner order window class (previously I called this the drop off)
Inherit functionality from sprite cluster
Fix on loop and other functions accordingly
Have this class interface with the order class to check if the sprite that was dropped off is the one that order specified.
Have this class interface with feedback to tell the user whether or not the order is correct
Figure out how to drop the sprite on this object and have the sprite removed from the food_group and make it and its rect object disappear from the screen
Complexity Beau: 1 The diner order window should just be stationary, right?
