// History:
//    Ed Frank      17 Nov 96         Creation of first version
//    Ed Frank      02 Dec 97         -Make abstract via pure virt dtor
//                                    -Add dumpName()
//                                    -Move print impl. into derivatives
//                                    -Move stuff to .cxx (no longer inline)
//
// Bugs:
//    I'd like to have print(ostream&) pure virtual, but then the Sun debugger
//    seems unable to function.
