/**
* Ivy software bus bench tester
*
* @author Yannick Jestin <yannick.jestin@enac.fr>
*
* (c) CENA 1998-2004
* (c) ENAC 2005-2011
*
* a program with 2 busses testing
* - the rendez vous
* - the IvyMessageListener interface
* - disconnect part of the IvyApplicationListener interface
*
* CHANGELOG
* 1.2.6
* - added a timestamp to facilitate the batch processing
* - no more necessary to invoque system.exit() when both busses have left.
* it used to produce an Exception ...
