This attribute gives the total number of Objects currently in
existence in the same class as the Object whose attribute value
is requested. This count does not include Objects which belong
to derived (more specialised) classes.
This attribute is mainly intended for debugging. It can be used
to detect whether Objects which should have been deleted have,
in fact, been deleted.
