//  Description: Returns a newly-allocated Node that is a shallow copy
//               of this one.  It will be a different Node pointer,
//               but its internal data may or may not be shared with
//               that of the original Node.

//               operator.  It may be overridden in derived classes to
//               include some information relevant to the class.
