Detailed Description

template<typename Point, int Dimension = -1, typename Strategy = strategy::compare::default_strategy>
struct boost::geometry::less< Point, Dimension, Strategy >

Less functor, to sort points in ascending order.

This functor compares points and orders them on x, then on y, then on z coordinate.

Template Parameters:

	Geometry	the geometry
	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
	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>.
