 forward the signal.  This is useful to track signals when there is a dynamic
 set of containers and layouts wrapping the widget.
    - signal_name string

- wibox.container.arcchart:disconnect_signal (name, func)
- 
    Disconnect to a signal.

- 
    Connect to a signal weakly.  This allows the callback function to be garbage
 collected and automatically disconnects the signal when that happens.
Warning: Only use this function if you really, really, really know what you are doing. - name string The name of the signal
