Definition

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.
