8    Shows the internals of the QUEUE protocol. Imlements QUEUE.Observer, gets called before an event
9    is added to the (internal) up- or down-queue of QUEUE (<em>not</em>Protocol !). This allows
10    to see what's going on in QUEUE. QUEUEView can also query the attributes of QUEUE, e.g. up_vec,
11    dn_vec etc.<br>
12    QUEUEView is implemented as a JPanel, and not as a JFrame, so it can be displayed inside the
13    Debugger's own view.
