class BSplineSurface from PGeom inherits BoundedSurface from PGeom

        ---Purpose : Definition  of  a B-spline   Surface   (it can be
        --         rational,  periodic and   non uniform) The  maximum
        --         degree  of  the  normalized B-spline   functions is
        --         limited to 9 in this package.
        --
