/**
* \ingroup PkgBGLRef
* \file CGAL/boost/graph/graph_traits_inheritance_macros.h
* Convenience header file defining the necessary specializations and overloads to make a
* class, inheriting from a model of a face graph concept, a model of that face graph concept itself.
* Prior to the inclusion of this header, specific macros must be defined and those macros will be
* undefined automatically when processing to the inclusion of this header.
* It is possible to include the header several times if the operation must be done for several classes.
* The macros that must be defined are the following:
* - `CGAL_GRAPH_TRAITS_INHERITANCE_CLASS_NAME`: the inheriting class. If it is a template class, it must be instantiated parameters named as in `CGAL_GRAPH_TRAITS_INHERITANCE_TEMPLATE_PARAMS` or parameters available in the scope including the header;
* - `CGAL_GRAPH_TRAITS_INHERITANCE_BASE_CLASS_NAME`: the base class. it must be instantiated parameters named as in `CGAL_GRAPH_TRAITS_INHERITANCE_TEMPLATE_PARAMS` or parameters available in the scope including the header;
* - `CGAL_GRAPH_TRAITS_INHERITANCE_TEMPLATE_PARAMS`: (optional) if the inheriting class, a list of template parameters separated by commas (`,`) including `class/typename/integral type`.
*
* Some examples are provided in \ref Surface_mesh/sm_derivation.cpp and \ref Polyhedron/poly_derivation.cpp.
