Operations
A model of this concept must provide:
Kernel::FT	operator() (const Kernel::Circle_2 &c)
	returns the squared radius of c.
Kernel::FT	operator() (const Kernel::Point_2 &p, const Kernel::Point_2 &q, const Kernel::Point_2 &r)
	returns the squared radius of the circle passing through p, q and r. More...
Kernel::FT	operator() (const Kernel::Point_2 &p, const Kernel::Point_2 &q)
	returns the squared radius of the smallest circle passing through p, and q, i.e. one fourth of the squared distance between p and q.
Kernel::FT	operator() (const Kernel::Point_2 &p)
	returns the squared radius of the smallest circle passing through p, i.e. $0$.
