CGAL 6.0  3D Simplicial Mesh Data Structures

#include <CGAL/Simplicial_mesh_cell_base_3.h>
CGAL::Triangulation_cell_base_3< typename Traits, typename TDSCb >.
The class Simplicial_mesh_cell_base_3
is a model of the concept SimplicialMeshCellBase_3
.
It is designed to serve as cell base class for 3D simplicial mesh data structures. It stores and gives access to data about the complex the cell belongs to, such as the subdomain it belongs to or surface it takes part to.
Gt  is the geometric traits class. It must be a model of the concept TriangulationTraits_3 
SubdomainIndex  Type of indices for subdomains of the discretized geometric domain. Must be a model of CopyConstructible , Assignable , DefaultConstructible and EqualityComparable . The default constructed value must match the label of the exterior of the domain (which contains at least the unbounded component). It must match MeshDomain_3::Subdomain_index when used for mesh generation. 
SurfacePatchIndex  Type of indices for surface patches (boundaries and interfaces) of the discretized geometric domain. Must be a model of CopyConstructible , Assignable , DefaultConstructible and EqualityComparable . The default constructed value must be the index value assigned to a non surface facet. It must match MeshDomain_3::Surface_patch_index when used for mesh generation. 
Cb  is the cell base class from which Simplicial_mesh_cell_base_3 derives. It must be a model of the concept TriangulationCellBase_3 .
