Operations
A model of this concept must provide:
bool	operator() (const Kernel::Line_2 &l1, const Kernel::Line_2 &l2)
	returns true, if l1 and l2 are parallel or if one of those (or both) is degenerate.
bool	operator() (const Kernel::Ray_2 &r1, const Kernel::Ray_2 &r2)
	returns true, if r1 and r2 are parallel or if one of those (or both) is degenerate.
bool	operator() (const Kernel::Segment_2 &s1, const Kernel::Segment_2 &s2)
	returns true, if s1 and s2 are parallel or if one of those (or both) is degenerate.
