 TGeoCtub - a tube segment cut with 2 planes. Has 11 parameters :
            - the same 5 as a tube segment;
            - x, y, z components of the normal to the -dZ cut plane in
              point (0, 0, -dZ);
            - x, y, z components of the normal to the +dZ cut plane in
              point (0, 0, dZ);
