SphericalKernel::CompareZToRight_3

An object fo of this type must provide:

Comparison_result
fo ( SphericalKernel::Circular_arc_3 a0 ,
SphericalKernel::Circular_arc_3 a1 ,
SphericalKernel::Circular_arc_point_3 p )
Compares the z-coordinates of the intersection points of both arcs with a meridian anchored at the poles of the context sphere used by the function SphericalKernel::compare_z_to_right_3_object, at a theta-coordinate infinitesimally greater that the theta-coordinate of point p.
Precondition:  a0 and a1 lie on the context sphere used by the function SphericalKernel::compare_z_to_right_3_object, a0 and a1 are theta-monotone, p lies on a0 and a1 and is not a theta-extremal point of the supporting circle of a0 or a1.
