       The DFPUpdate class is used to specify a Broyden, Fletcher, Goldfarb, and Shanno hessian update scheme.

       This hessian update method is the recommended method for use with QNewtonOpt objects.

voidsc::BFGSUpdate::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::DFPUpdate.
