in order to avoid both virtual classes and ambiguous definitions all

In other words we cannot derive and add in a single derivation step
(with multiple ancestor), both the real (non-empty) normal and color but
we have to build the type a step a time (deriving from a single ancestor at a time).

/*
These are the three main classes that are used by the library user to define its own Facees.
The user MUST specify the names of all the type involved in a generic complex.
so for example when defining a Face of a trimesh you must know the name of the type of the edge and of the face.
Typical usage example:
A Face with coords, flags and normal for use in a standard trimesh:
class MyFaceNf : public FaceSimp2< VertProto, EdgeProto, MyFaceNf, face::Flag, face::Normal3f > {};
A Face with coords, and normal for use in a tetrahedral mesh AND in a standard trimesh:
class TetraFace : public FaceSimp3< VertProto, EdgeProto, TetraFace, TetraProto, face::Coord3d, face::Normal3f > {};
A summary of the components that can be added to a face (see components.h for details):
VertexRef
Mark //Incremental mark (int)
VTAdj //Topology vertex face adjacency
(pointers to next face in the ring of the vertex
TTAdj //topology: face face adj
pointers to adjacent faces
