SphericalKernel::CompareZAtTheta_3

An object fo of this type must provide:

Comparison_result	fo ( SphericalKernel::Circular_arc_3 a0 , SphericalKernel::Circular_arc_3 a1 , SphericalKernel::Vector_3 m )
		compares the z-coordinates of the two intersections points of a0 and a1 with the meridian defined by m (see section 14.2). Precondition:  a0 and a1 lie on the context sphere used by the function SphericalKernel::compare_z_at_theta_3_object. m ≠ (0,0,0) and the z-coordinate of m is 0. Arcs a0 and a1 are -monotone and both intersected by the meridian defined by m (see section 14.2).
Comparison_result	fo ( SphericalKernel::Circular_arc_point_3 p , SphericalKernel::Circular_arc_3 a )
		given a meridian anchored at the poles of the context sphere used by the function SphericalKernel::compare_z_at_theta_3_object, and passing through point p, compares the z-coordinate of point p and that of the intersection of the meridian with a. Precondition:  a and p lie on the context sphere used by the function SphericalKernel::compare_z_at_theta_3_object, arc a is -monotone and the meridian passing through p intersects arc a.
