Mael Rouxel-Labbé a0427ec756 Fixed abusing Triangulation_cell_base_3 for Delaunay triangulations ... TriangulationCellBase_3 does not request a circumcenter; DelaunayTriangulationCellBase_3 does. Delaunay_triangulation_3 only compiled because Triangulation_cell_base_3 (and Triangulation_ds_cell_base_3 !) provided circumcenter() operators and DT3 inherited T3's TDS. - The circumcenter() functions are removed where they shouldn't exist - DT3 uses DT_cell_base_3 as cell base instead of T_cell_base_3 - Concepts/Classes that supposedly only required TriangulationCellBase_3 and then built Delaunay triangulations with that (Alpha Shapes, etc.) are upgraded to request DelaunayTriangulationCellBase_3 (anyway, it wouldn't compile if you actually provided a model of TriangulationCellBase_3) - Fixed various wrong templates in classes/concepts such as MeshVertexBase_3 not refining RegularTriangulationVertexBase_3 and (only in the doc) defaulting to Triangulation_vertex_base_3 - Removed the deprecated class (for 4+ years) T_cell_base_with_circumcenter		2018-04-26 13:21:53 +02:00
