//
// = DESCRIPTION
// This is a utility class is to be used by clients of the Notification
// Service to implement the servant for CosNotifyComm::PushConsumer
//
// = HOW-TO
// 1. Derive from Notify_ProxyConsumer and implement <push>.
// 2. Create the servant on the heap.(refcounted servant).
// 3. Initialize the object, provide a POA.
// 4. To connect, call <connect>, this will activate the object in the POA.
// You must provide a ConsumerAdmin to <connect>.
// 5. To disconnect, call <disconnect> this will also deactivate the object.
