Your mission is to make a simulation of a room.  

The inside of the room is 20x20 feet.  The rooms walls are always 20 degrees.  

The room has a window that is always 10 degrees.  This wall starts at
(0,4) and goes to (0,7).  It includes the endpoints.

The room has an electric heater that is 200 degrees.  It is ia (5,5).

Every other bit of the room has a tempurature that is the average of
the four nearest neighbors.

Points:
	The walls are always 20 degrees.
	The windows is as above
	The heater is as above
	Clicking drops a new heater into the room.
	Any one feature you want (at least 10 lines of code).
	Compute the minimum, maximum, and average tempature of the room.
	Dragging the mouse around moves a heater around.
