Required types and functors for the LinearCellComplexTraits concept. This geometric traits concept is used in the Linear_cell_complex class.
static unsigned int  ambient_dimension;  The ambient dimension, must be >1. 
LinearCellComplexTraits::FT  
a number type that is a model of FieldNumberType.
 
LinearCellComplexTraits::Point  
point type.
 
LinearCellComplexTraits::Vector  
vector type.

LinearCellComplexTraits::Construct_translated_point  
Functor that provides Point operator() (const Point& p, const Vector& v),
which constructs the translation of point p by vector v, and
Point operator() (const CGAL::Origin&, const Vector& v),
which constructs the translation of a point at the origin by vector v
(used in Linear_cell_complex::barycenter).
 
LinearCellComplexTraits::Construct_vector  
Functor that provides Vector operator() (const Point& p1, const Point& p2)
which constructs a vector as the difference of points p2p1, and
