CGAL 5.5  2D Triangulations

Inherited by CGAL::Triangulation_face_base_with_id_2< class, class >.
The concept TriangulationFaceBase_2
describes the requirements for the base face class of a triangulation data structure that is itself plugged into a basic triangulation or a Delaunay triangulation.
This concept refines the concept TriangulationDSFaceBase_2
and could add geometric information. In fact, currently the triangulations do not store any geometric information in the faces and, thus this concept is just equal to TriangulationDSFaceBase_2
and only provided for symmetry with the vertex case.
