These are the three main classes that are used by the library user to define its own vertexes.
The user MUST specify the names of all the type involved in a generic complex.
so for example when defining a vertex of a trimesh you must know the name of the type of the edge and of the face.
Typical usage example:
A vertex with coords, flags and normal for use in a standard trimesh:
class VertexNf : public VertexSimp2< VertexNf, EdgeProto, FaceProto, vert::Coord3d, vert::Flag, vert::Normal3f > {};
A vertex with coords, and normal for use in a tetrahedral mesh AND in a standard trimesh:
