     Tries to minimize the sum (square(||Qui - Bi*Pi||)) where Pui describe the approximating Bezier curves'Poles and Qi the MultiLine points with a parameter ui. In this algorithm, the parameters ui are the unknowns. The tolerance required on this sum is given by Tol. The desired degree of the resulting curve is Deg.
    bool IsDone () const
     returns True if all has been correctly done.
    AppParCurves_MultiCurve Value () const
     returns all the Bezier curves approximating the MultiLine SSP after minimization of the parameter.
    double Error (const int Index) const
     returns the difference between the old and the new approximation. An exception is raised if NotDone. An exception is raised if Index<1 or Index>NbParameters.

     returns the maximum difference between the old and the new approximation.
