Detailed Description
       The PowellUpdate class is used to specify a Powell hessian update.

       This hessian update method is the recommended method for use with
       transition state searches (the EFCOpt class can be used for transition
       state searches).

Member Function Documentation
   void sc::PowellUpdate::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::HessianUpdate.
