        As a rule of thumb: describe what all custom functions and object 
        methods do.

        formatting as described in the Udacity JavaScript Style Guide.

I did not like this project.  I am not a gamer and I had a hard time 
understanding the flow of the program since most of the heavy lifting was 
done by the engine that was provided.  I tried hard to at least code it 
using the OO techniques.
