\brief Less functor, to sort points in ascending order.
\ingroup compare
\details This functor compares points and orders them on x,
then on y, then on z coordinate.
\tparam Geometry the geometry
\tparam Point the geometry
\tparam Dimension the dimension to sort on, defaults to -1,
indicating ALL dimensions. That's to say, first on x,
on equal x-es then on y, etc.
If a dimension is specified, only that dimension is considered
\tparam Strategy underlying coordinate comparing functor,
defaults to the default comparison strategies
related to the point coordinate system. If specified, the specified
strategy is used. This can e.g. be std::less<double>.
