Manages contact between two shapes. A contact exists for each overlapping AABB in the broad-phase (except if filtered), so a contact object may exist that has no contact points. (b2ContactSim)

The C #if B2_ENABLE_VALIDATION bodyIdA/bodyIdB fields are always present here; they only feed validation.
