The ContactTrackerSubsystem will invoke this method for any pair of contact surfaces that is already being tracked, or for which the static broad phase analysis indicated that they might be in contact now.
Only position information is available. Note that the arguments and Contact object surfaces must be ordered by geometry type id as required by this tracker.
Implements SimTK::ContactTracker.
