Bootstrap Stored Musical State

Justin Nearing
On music platform trigger, add the note associated with the platform to Game State.
Note state should be an array
Array should live in Game State

This one should remain relatively simple. While playing, we want to store the users actions.

I don't see this being any more complicated than an array of Notes to start with.

Eventually might want some sort of object storing things like which note, when played, loudness, etc. But that depends on a lot of undecided things.
