/**
 * <p>
 * The class testNcdPerfDataBean demonstrates the use of some of the beans
 * in the uk.co.westhawk.snmp.beans packages. It shows a UI in which the
 * user can configure the bean properties.
 * </p>
 *
 * <p>
 * When triggering the menu button at the background, a property dialog 
 * will popup.
 * The user can configure the host name, the port number, the community
 * name and the update interval. When the OK or Apply button is pressed
 * NcdPerfDataBean is activated. Via the PropertyChangeEvent it
 * will provide the UI with the list of current names.
 * </p>
 *
 * <p>
 * The "Try it" button in the dialog activates the IsHostReachableBean, 
 * who will probe
 * the configured host and signals the UI since when the host was up.
 * </p>
 *
 * <p>
 * The values of the property dialog can also be configured via 
 * the properties file. 
 * The action() method still has to be called, either via java
 * code, or by pressing the button in the dialog.
 * </p>
 *
 * <p>
 * The name of the properties file can be passed as first argument to
 * this application. If there is no such argument, it will look for
 * <code>testNcdPerfDataBean.properties</code>. If this file does not exist, the
 * application will use default parameters.
 * </p>
 *
 * <p>
 * The speed will be shown as a Graph, its values displayed as 10log.
 * The memory will also be shown as a Graph, but with normal values
 * displayed.
 * </p>
