/**
 * Like BasicRace, only this version uses the property setter capabilities
 * of the framework.  Instead of manually calculating the position of the
 * car, we have the framework do it for us, based on how we set up the
 * PropertySetter object.  All of this is done at
 * construction time and we merely start or stop the animation based on
 * the Go/Stop buttons at runtime.
