            ~RosenBrock();
            Vector<double>* 	getGradient(Model<double>&);
            Vector<double>* 	getGradient(Model<long>&);
            const char*  className() const;

        \fIProtected members\fP
            double 		realPerformance(Model<double>&);
            double 		realPerformance(Model<long>&);

DESCRIPTION
    RosenBrock
     This is an analytical function for testing optimization
     algortithms. The function looks like
       f = 100. * (m[1]-m[0]^2)^2 + (1-m[0])^2.
     See also ObjFcn
    

CAVEATS
     RosenBrock currently only takes Models either double 
     or long integer. It is mostly because I tried to avoid using
     templates, due to the guliness of template features in G++. 
     Hopefully, this could be changed soon.
