*
* This is a class used to retrieve the LoadManager reference and
* create the Object Group. Servants add themselves to the object
* group and the object group reference is published to the clients.
* Clients then invoke the "servant operations" on the LoadManager
* itself. At this point the Load Balancing cycle starts.
