Registers the listener to receive notifications with the specified notification name and/or containing the given object.
When a matching notification is posted, the 'callBackMethodName' message will be sent to the listener with a single PNotification argument. If the notification name is null, the listener will receive all notifications with an object matching the given object. If the object is null, the listener will receive all notifications with the notification name.
