[Cs3] Templated Design Pattern

primitive operations: implemented in C++ as pure virtual functions, do
	  not provide default implementation and must be overridden by the
	  derived class

hooks: provide a derfault implementation and _may_ be override by the
       derived class if different behavior is desired.
