finds out whether T_functor is tunneled, i.e. whether the functor chain contains a functor derived from sigx::tunnel_base.
To investigate the fact that there exists one functor derived from sigx::tunnel_base, this template struct cascades down the functor chain. e.g. bind_functor - tunnel_functor - member_functor
The template argument T_functor is the functor type. I_isadaptor indicates whether T_functor inherits from sigc::adaptor_base. I_istunnel indicates whether T_functor inherits from sigx::tunnel_base.
