omphalos.event.ioDisconnect
omphalos.event.ioDisonnect(() => { omphalos.log.debug(`asset ${omphalos.asset.name} has disconnected`);})This event is raised whenever the asset has been disconnected from the back end system.
Invoking this function is equivalent to a call to omphalos.event.on(), and
thus returns a function you can use to cancel the event listener registration
as needed.
