The minimize api only reports the finalEnergy. Can we also get the final gradient norm?

inline int minimize(Foo& f, Vector& x, Scalar& fx)

becomes

inline int minimize(Foo& f, Vector& x, Scalar& fx, Scalar &gnorm)

Good point. I'll consider to add an overloaded function to report more information, including the gradient and its norm.
