     obj.equal?( anObject ) -> true or false
------------------------------------------------------------------------
     Returns true if obj and anObject have the same object ID. This
     method should not be overridden by subclasses.

     obj == anObject -> true or false
------------------------------------------------------------------------
     Equality---At the Object level, == returns true only if obj and
     anObject are the same object. Typically, this method is  
     overridden in descendent classes to provide class-specific
     meaning.
