* TestEvents - test the events
*
* The following test assumes that we know the content of the
* graph as we get elements, add and change them. Therefore, the TestBook.xml
* file and this java test should be kept in sync.
*
* Test the following:
*
* listener on the root - change event for add/change/remove on the same root bean
* listener on the root - change event for add/change/remove
* on a sub node bean (propagation)
* listener on the root and on a subnode: test no reception, both reception and
* only one reception
* listener on a specific property
* remove listeners
* indexed and non indexed property events
* check utility methods to get the index, name and parent bean
* from an event name (graphManager methods)
* remove a subtree - get event within the subtree (no propagation)
* and within the original tree (propagation)
*
