\ccInclude{CGAL/NewKernel_d/Cartesian_wrap.h}

\ccDefinition
This class derives from a \ccc{Kernel} \ccc{Base} and replaces a number
of types (point, segment) with wrappers that have intuitive member
functions that call the corresponding functors. For instance, the
constructors forward to \ccc{Functor<Construct_ttag<Tag>>::type},
\ccc{Point::operator[]} forwards to
\ccc{Functor<Compute_cartesian_coordinate_tag>::type},
\ccc{operator+(Vector,Vector)} forwards to
\ccc{Functor<Construct_sum_of_vectors_tag>::type}, etc.

For stateful kernels, the wrappers will store a pointer to the kernel
instance. This means in particular that for such a kernel, one can't
just create a point from its coordinates (like \ccc{Point M(1,2,3);}),
they have to create it using some functor or an operation on existing
objects.

\ccImplementation
The implementation \emph{tries} to avoid any extra copying that could be
caused by the wrapping.
