Class CGAL::Conforming_constrained_Delaunay_triangulation_cell_base_3< Traits, Cell_base >

After discussion with Jane. Maybe there should be a second pair of Vb/Cb, designed to model the concepts of simplicial mesh and remeshing.

Class ConformingConstrainedDelaunayTriangulationTraits_3

Add the requirements in the concept ConformingConstrainedDelaunayTriangulationTraits_3.

Module PkgCT_3Ref

Explain what is a CDT. Why a given input, like a polyhedron, might not admit a constrained Delaunay triangulation. Explain "conforming to the faces of a polygon mesh".
