-- Do not use concept names as template names in the doc
-- Fixed point / point_3 issues and other problems of coherence between concept
and model
-- Fixed some wrong refinement relationships
When the geom_traits given as parameter of `circumcenter` and/or
`weighted_circumcenter` was deriving from the cell base GT
(first template parameter), the gt was up-casted to the
cell base GT, and the function construct_circumcenter_3_object()
(or construct_weighted_circumcenter_3_object()) not
called on the right geom traits type --> possibly missing
the actual input of the function (the robust_circumcenter_traits in Mesh_3)
we add a static assert to check at compile time that point types are the same

weighted_circumcenter() replaces circumcenter() in the regular framework,
which is not a member of TriangulationCellBase_3 anymore.
Triangulation_cell_base_with_circumcenter_3 is deprecated and replaced by:
Delaunay_triangulation_cell_base_with_circumcenter_3
and
Regular_triangulation_cell_base_with_circumcenter_3.
Implement the changes in documentation, Triangulation_3 code and Mesh_3 code.
