an object.  Every class {\tt X} that implements copying should provide
an {\tt \_CopyX} routine that copies relevant data from an old object
to a new object, so that subclass copy routines may call this routine
to copy the superclass's data.  The {\tt CopyX} routine just creates a
new object of the appropriate type and then calls {\tt \_CopyX} to copy
the data.
