Detailed Description

This is a unique integer Id assigned to each contact pair when we first begin to track it.

The Id persists for as long as we are tracking this pair of surfaces; it is the basis for our notions of "the same contact" and "continuing contact". After we stop tracking a contact pair, its Id will not refer to any contact pair and any given Id will not be reused for a very long time; hence, these will typically be large numbers even if there are only a small number of contacts at any given moment. The Id is unique only within an instance of ContactTrackerSubsystem.
