 * @brief GModelSpatialRadialShell class extension
 *
 * The eval(GSkyDir&) and eval_gradients(GSkyDir&) need to be defined in the
 * extension to force swig to build also the interface for these methods that
 * are implemented in the base class only. It's not clear to me why these
 * methods are not inherited automatically. Maybe this could also be handled
 * by a %typemap(typecheck) construct.
