double	Root () const override
	Returns the previously calculated root.

bool	SetFunction (const IGenFunction &f, double xlow, double xup) override
	Sets the function for the rest of the algorithms.

virtual bool	SetFunction (const ROOT::Math::IGenFunction &, double, double)
	Sets the function for the rest of the algorithms.

virtual bool	SetFunction (const ROOT::Math::IGradFunction &, double)
	Sets the function for algorithms using derivatives.
