 * Instructions:
 *     Fill in the RoomSet(Room) constructor
 *     Pick a color at random (currently, color 0,0,0 is picked
 *       read the Color API (clickable from the lab web page description)
 *       to see how to use new Color(int,int,int)
 *     Implement union
 *     Try the selfTest()
 *     Implement addRoom
 *     Test some more
