Now that a lot of the logic has been written for the maze, we need to start introducing the concepts needed for the music maze to take shape. Concepts like the music notes should be implemented either as a view feature or as a model feature, this should be driven by a design choice and then made.

The music maze at this point is now capable of being played as a "walkable" tree, but needs a bit more refinement before it can be expressed as a proper music maze.
