        This function does not require that the analog input is online at the time
        it is invoked. The returned object is nevertheless valid.
        Use the method YAnButton.isOnline() to test if the analog input is
        indeed online at a given time. In case of ambiguity when looking for
        an analog input by logical name, no error is notified: the first instance
        found is returned. The search is performed first by hardware name,
        then by logical name.

        If a call to this object's is_online() method returns FALSE although
        you are certain that the matching device is plugged, make sure that you did
        call registerHub() at application initialization time.

                YBUZZER2.anButton1.
