Run-time, the RaceTracker object monitors objects passing through waypoints and maintains
statistics about the race, like current standing and completed laps.
I link the waypoints and the car to the RaceTracker object to enable monitoring for them.
I also specify, on the property dialog for the RaceTracker object, the relationship type for
each monitored object.
