SphericalKernel::IsThetaMonotone_3

An object fo of this type must provide:

bool	fo ( SphericalKernel::Circular_arc_3 a )
		Tests whether the arc a is -monotone, i.e. the intersection of any meridian anchored at the poles of the context sphere used by the function SphericalKernel::is_theta_monotone_3_object and the arc a is reduced to at most one point in general, and two points if a pole of that sphere is an endpoint of a. Note that a bipolar circle has no such arcs. Precondition:  a lies on the context sphere used by the function SphericalKernel::is_theta_monotone_3_object, and the supporting circle of a is not bipolar.
