Detailed Description

visitor: This is the "dynamic polymorphism" part.

Abstract base class for all the visitors (cf GoF Visitor Design Pattern) the whiteboard uses. visitor does not inherit from enable_visit_all because it tends to make it more "difficult" for derived classes to inherit from both visitor and enable_visit_all.
