/**
 * <p>
 * The class testAscendActiveSessionBean 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>
 * The user can configure the host name, the port number, the community
 * name and the update interval. When the action button is pressed
 * AscendActiveSessionBean is activated. Via the PropertyChangeEvent it
 * will provide the UI with the information about the Active Session.
 * </p>
 *
 * <p>
 * The "Try it" button activates the IsHostReachableBean, who will probe
 * the configured host and signals the UI since when the host was up.
 * </p>
