> The daemon expression currently runs until it's killed. This ticket will add a new *terminate*
parameter to the daemon expression that will allow the daemon to shut itself down when it's
finished processing a topic.
> There are a couple of small changes that need to be made to allow the daemon to terminate
on it's own:
> 1) The daemon will need to be passed the Map of all daemons in the /stream handler. This
will allow the DaemonStream to remove itself from the Map when it terminates.
> 2) Logic needs to be added for the daemon to exit it's run loop if the topic signals
it had a zero Tuple run. The *sleepMillis* value in the EOF Tuple can be used for this purpose.
If sleepMillis is greater then 0 then this signals a zero Tuple run.
