Use CGAL/Triangulation_vertex_base_with_info_3.h and 
Triangulation_cell_base_with_info_3.h.

For example, if you want to add an unsigned integer to both structures, you 
can do something like:


// CGAL headers
#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/Triangulation_vertex_base_with_info_3.h>
#include <CGAL/Triangulation_cell_base_with_info_3.h>
#include <CGAL/Delaunay_triangulation_3.h>

using K = CGAL::Exact_predicates_inexact_constructions_kernel;
using Triangulation = CGAL::Triangulation_3<K>;
// Used so that each timeslice is assigned an integer
using Vb = CGAL::Triangulation_vertex_base_with_info_3<std::uintmax_t, K>;
// Used to mark cell type
using Cb = CGAL::Triangulation_cell_base_with_info_3<std::uintmax_t, K>;
