Step 6: The Document-View model that Mircosoft uses has a central application class that manages the WinMain portion of the program. Later on the registry founctions will ba added, but for now just the size of the playing field and the number of colours vaeiables need be created. Note: It would be a good idea that the limits of the Board class be enforced at this point but this can be compensated for at the game set up. (It is still a possible problem but only if the limits are not enforced constantly.)
