Comments in Maze Example

[jrc03c]

I need to add some comments in the maze example to show the inheritance of variables like position in the Player class. (from this PR)

Please Help! I am very confused about how to set and change the camera position in this library.

[jrc03c]

@krhobeck, you can manually set the camera position by using the position property of the camera. The position is a 3D PVector. So, for example:

cam.position = new PVector(5, -3, 7.2);

Ok, that clears up everything, I was doing position = new PVector(x, y,z); and it wasn't working.
