CGAL 5.6  Linear Cell Complex

#include <CGAL/Linear_cell_complex_traits.h>
K.
This geometric traits concept is used in the Linear_cell_complex_for_combinatorial_map
and Linear_cell_complex_for_generalized_map
classes.
It can take as parameter any model of the concept Kernel
(for example any CGAL kernel), and defines inner types and functors corresponding to the given dimension.
d  the dimension of the kernel, 
K  a model of the concept Kernel if d==2 or d==3 ; a model of the concept Kernel_d otherwise. Equal by default to CGAL::Exact_predicates_inexact_constructions_kernel if d is 2 or 3, and is CGAL::Cartesian_d<double> otherwise. 
Note that the default argument used for K
when d > 3 does not use exact predicates because operations that use predicates are only defined in 2D and 3D.
