[ns] Monitoring average queue

[Sven Ostring <ostrinsa@elec.canterbury.ac.nz>]

What sort of Tcl code padding is needed around the procedure:

$ns monitor-queue $node1 $node2 $qtrace $interval

to either dump the queue average regularly to $file, or to send it at 
$now to the standard output?

Thanks,
Sven.
