Making sure I remember how to delete files in a commit.
Added the animator, but it does not respond fast enough yet to timed
events.
Figured out how to change the polling interval. MUCH faster now.
TONS of changes. I made fixes according to Noah's comments, and finally
figured out a few bugs: 1. figured out how to make playing from the middle
of the song work; 2. figured out how to properly check for errors when
loading music; 3. figured out a solution for skipping beats when the music
ends because the beats file runs out; 4. figured out how to avoid throwing
timed events that occur before the place where the music is started
