   void sc::GDIISOpt::save_data_state (StateOut &) [virtual]
       Save the base classes (with save_data_state) and the members in the same order that the
       StateIn CTOR initializes them. This must be implemented by the derived class if the class
       has data.

       Reimplemented from sc::SavableState.

   int sc::GDIISOpt::update () [virtual]
       Take a step. Returns 1 if the optimization has converged, otherwise 0.

       Implements sc::Optimize.
