Mock up a Game Controller

[nhandler]

We will not know all of the functions we need for the game controller until we write the actual game. However, we should still create some stubbed out functions for things that we know we will need.

We should make sure that we have at least one request, one modify, and one error. We are not limited to stubbing out only these functions, but this is the absolute minimum.

Nathan's code on this looks good. Closing issue for him.
