10  * Mock object for a PropertyChangeListener.
11  * This mock object can be used in verifying the event propagation mechanism
12  * of beans. You can set the information you expect from a PropertyChangeEvent
13  * as well as the number of events. If you expect more than one event, only the
14  * actual values of the last event are stored.
