* TODO: Fix description
* This is a class used to retrieve the NamingManager 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 NamingManager
* itself. At this point the Load Balancing cycle starts.
