Kernel::ComputeSquaredRadius_2

Kernel::FT	fo.operator() ( Kernel::Circle_2 c)
		returns the squared radius of $$c.
Kernel::FT	fo.operator() ( Kernel::Point_2 p, Kernel::Point_2 q, Kernel::Point_2 r)
		returns the squared radius of the circle passing through $$p, $$q and $$r. Precondition: p, q and r are not collinear.
