V2.2

Radar circles now draw through a separate class so that the radii can be
changed when a key is pressed to create a pulsating effect. When the
keys 'j'  'k' 'l' ';' ' ' are pressed, the circle they correspond to
will quickly pulse. Rhythm circles are now displaying through their x
and y coordinates at the correct time. Most likely circles will display
based on angle later on. Circles also need a selector sweeping
informational, which will allow us to display them at the correct point
in the song.
