MeshCriteria_3 Concept Reference

## Definition

The Delaunay refinement process involved in the template functions `CGAL::make_mesh_3()` and `CGAL::refine_mesh_3()` is guided by a set of elementary refinement criteria that concern either mesh tetrahedra or surface facets. The refinement criteria for tetrahedra are described through the concept `MeshCellCriteria_3` while the refinement criteria for surface facets are described by the concept `MeshFacetCriteria_3`. The concept `MeshCriteria_3` encapsulates these concepts.
