Kernel::ComputeSquaredRadius_3

Kernel::FT	fo.operator() ( Kernel::Sphere_3 s)
		returns the squared radius of $$s.
Kernel::FT	fo.operator() ( Kernel::Point_3 p, Kernel::Point_3 q, Kernel::Point_3 r, Kernel::Point_3 s)
		returns the squared radius of the sphere passing through $$p, $$q, $$r and $$s. Precondition: p, q, r and s are not coplanar.
Kernel::FT	fo.operator() ( Kernel::Point_3 p, Kernel::Point_3 q, Kernel::Point_3 r)
		returns the squared radius of the sphere passing through $$p, $$q and $$r, and whose center is in the plane defined by these three points.
