/**
 * @class LB_Factory_Server
 *
 * @brief Encapsulate the test in class.
 *
 * 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.
