The class Surface_mesh_vertex_base_3<Gt,Vb> is a model of the concept SurfaceMeshVertexBase_3. It is designed to serve as vertex base class in a triangulation class Tr plugged in a Surface_mesh_complex_2_in_triangulation_3<Tr> class.
The first template parameter is the geometric traits class.
The second template parameter is a base class. It has to be a model of the concept TriangulationVertexBase_3 and defaults to Triangulation_vertex_base_3 <GT>.
