Notification and ServiceGroups
NotificationSource subscribe implemented with subscribeByServiceDataNames. Periodic notification is not supported - notification only occurs when the SDE changes.
NotificationSubscription implemented using a separate process, this is not efficient and will not scale.
NotificationSink a sample NotificationSink Grid Service is provided that implements deliverNotification.
ServiceGroup PortType implemented.
ServiceGroupRegistration inherits ServiceGroup and supports add and remove. remove is implemented with matchByLocatorEquivalence.
ServiceGroupEntry - implemented as a separate process, not efficient and will not scale. (could use lazy instantiation or one giant Grid Service pretending to be lots of NotificationSubscriptions)
