//      Bertram Kopf (RUB) migrated to PandaRoot
//
// Bugs:
//    The class allows a defalt copy constructor and assignemtn op.
//    I'm not sure if this is right.  Since counters are supposed to
//    count the number of instances of the beasts exist, it doesn't
//    seem fair to assing one to another.  On the other hand, counters
//    may find use embedded inside other objects and I'm not sure
//    if we should allow an impact there by denying copies.
//    So, for now the user is on his own.  If he does a copy of one
//    of these, it will s.cxxeed...and he'll probably regret it.
//------------------------------------------------------------------------


// This class just counts up forever as instnaces are created.
// It does *not* count number of existing instances, i.e., there's
// no decrement in the destructor.
