// 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.
