I've already looked to Triangulation and Triangulation_data_structure but
Trangulation_data_structure is only parametrized with Cell_base and
Vertex_base and I need one that could also use some "Facet_base" so
deriving a new one from it could it be the right answer given that I still
want to use the other structures like Cell_hendle, Vertex_handle, etc.
