Add leg sep, diameter to Person
Don't create "mouse" person until button clicked
Made P1 cow gray instead of black
Made Leg position, velocity private (use getter)
Clone position, velocity before setting
Removed normalizeDistance(), use mapVelocity instead
Increase size to 1280x720
Return from draw when no people present
Only do particle system pushes if person is moving
Modified soccer collision logic
Soccer: draw ball at correct size, make it an outline
Correct for radius when bouncing off walls
