  //   Contacts the <Object_Group_Factory> in th Load Balancing Server
  //   to obtain a reference to the type of the <Object_Group>
  //   specified on the command line.  Then, queries the
  //   <Object_Group> for its id and members, and prints that
  //   information.  Finally, performs <number_of_invocations_>
  //   <Identity::get_name> calls, performing <Object_Group::resolve>
  //   before each <get_name> call in order to get the <Identity>
  //   reference to use for the call.  (This provides an example of
  //   fine-grained, i.e., per call,  Load Balancing among all the
  //   <Identity> objects registered with the <Object_Group> for the
  //   client's <get_name> calls.
