/**
* The <code> ServerDriver </code> class is a driver
* of the <code> ServerFrame </code> class. It automatically
* changes the states of the server a follows:
* listen for 10 sec, stop for 5 sec, close for 5 sec,
* listen for 20 sec, stop for 10 sec, listen for 10 sec,
* stop for 5 sec. This cycle is indefinitely repeated. <p>
* Type <code>java ocsftester.ServerDriver port_number</code> to start
* the server.<p>
* The window is red
* when the server is closed, yellow when the server is stopped
* and green when open.
