Operations
A model of this concept must provide:
Comparison_result	operator() (ArrTraits::X_monotone_curve_2 xc1, ArrTraits::X_monotone_curve_2 xc2, ArrTraits::Point_2 p)
	accepts two \(x\)-monotone curves xc1 and xc2 that have a common right endpoint p, and returns CGAL::SMALLER, CGAL::EQUAL or CGAL::LARGER according to the relative position of the two curves immediately to the left of \(p\).

Comparison_result ArrTraits::CompareYAtXLeft_2::operator()	(	ArrTraits::X_monotone_curve_2	xc1,
		ArrTraits::X_monotone_curve_2	xc2,
		ArrTraits::Point_2	p
	)

accepts two \(x\)-monotone curves xc1 and xc2 that have a common right endpoint p, and returns CGAL::SMALLER, CGAL::EQUAL or CGAL::LARGER according to the relative position of the two curves immediately to the left of \(p\).

Note that in case one of the \(x\)-monotone curves is a vertical segment (emanating downward from p), it is always considered to be below the other curve.
