Detailed Description
       The NonlinearTransform class transforms between two nonlinear
       coordinate systems.

       It is needed when a change of coordinates occurs	in the middle of an
       optimization.

Member Function	Documentation
   virtual void	sc::NonlinearTransform::transform_coordinates (const
       RefSCVector & x)	[pure virtual]
       Transform the coordinates.

       Implemented in sc::IdentityTransform.

   virtual void	sc::NonlinearTransform::transform_gradient (const RefSCVector
       & g) [virtual]
       Transform the gradient at a point in the	new coordinate system.
       transform_coordinates must be called first to give the point.

       Reimplemented in	sc::IdentityTransform.

   virtual void	sc::NonlinearTransform::transform_hessian (const
       RefSymmSCMatrix & h) [virtual]
       Transform the hessian to	the new	coordinate system. transform_gradient
       must be called first to initialize this routine.

       Reimplemented in	sc::IdentityTransform.

   virtual void	sc::NonlinearTransform::transform_ihessian (const
       RefSymmSCMatrix & ih) [virtual]
       Transform the inverse of	the hessian. transform_gradient	must be	called
       first to	initialize this	routine.

       Reimplemented in	sc::IdentityTransform.
