Vb.
The class Mesh_vertex_base_3 is a model of the concept MeshVertexBase_3. 
It is designed to serve as vertex base class for the 3D triangulation used in a 3D mesh generation process.
| Gt | is the geometric traits class. It must be a model of the concept RegularTriangulationTraits_3. | 
| MD | provides the types of indices used to identify the faces of the input complex. It must be a model of the concept MeshDomain_3. | 
| Vb | is the vertex base class. It has to be a model of the concept TriangulationVertexBase_3and defaults toTriangulation_vertex_base_3<Gt>. |
