Functions
template<typename Kernel >
Comparison_result	CGAL::compare_slope (const CGAL::Line_2< Kernel > &l1, const CGAL::Line_2< Kernel > &l2)
	compares the slopes of the lines `l1` and `l2`

template<typename Kernel >
Comparison_result	CGAL::compare_slope (const CGAL::Segment_2< Kernel > &s1, const CGAL::Segment_2< Kernel > &s2)
	compares the slopes of the segments `s1` and `s2`, where the slope is the variation of the `y`-coordinate from the left to the right endpoint of the segments.

template<typename Kernel >
Comparison_result	CGAL::compare_slope (const CGAL::Point_3< Kernel > &p, const CGAL::Point_3< Kernel > &q, const CGAL::Point_3< Kernel > &r, const CGAL::Point_3< Kernel > &s)
	compares the slopes of the segments `(p,q)` and `(r,s)`, where the slope is the variation of the `z`-coordinate from the first to the second point of the segment divided by the length of the segment.
