 Extrema_GenExtSS ()
 Extrema_GenExtSS (const Adaptor3d_Surface &S1, const Adaptor3d_Surface &S2, const Standard_Integer NbU, const Standard_Integer NbV, const Standard_Real Tol1, const Standard_Real Tol2)
 It calculates all the distances.
The function F(u,v)=distance(S1(u1,v1),S2(u2,v2)) has an
extremum when gradient(F)=0. The algorithm searchs
all the zeros inside the definition ranges of the
surfaces.
NbU and NbV are used to locate the close points
to find the zeros.

 the algorithm is done withS1
An exception is raised if the fields have not
been initialized.

Standard_Boolean IsDone () const
 Returns True if the distances are found.

Standard_Integer NbExt () const
 Returns the number of extremum distances.

Standard_Real SquareDistance (const Standard_Integer N) const
 Returns the value of the Nth resulting square distance.
