bool	compare_theta_z ( Circular_arc_point_3<SphericalKernel> p, Circular_arc_point_3<SphericalKernel> q, Sphere_3<SphericalKernel> sphere)
		Compares p and q according to the lexicographic ordering on and z-coordinates in the cylindrical coordinate system relative to sphere. Precondition:  p and q lie on sphere, but do not coincide with the poles of sphere.
