Detailed Description

Defines a visitor of the scene graph elements.

The Visitor follows a hierarchical visitor pattern (see http://c2.com/cgi/wiki?HierarchicalVisitorPattern) what enables to track entering and leaving composite entities - assemblies and instances.

Methods VisitEnter() returns true if the child elements of the assembly or a referred element of the instance should be visited. If the method returns false then they will not be visited. The method VisitLeave() will always be called.
