GET Operation Wait State
This state issues the Get indication to the Application on entry and then waits for the response.

Any OBEX operation will be cause a Protocol Error
Chaging the MObexServerNotifyAsync via CObexServer::Start() will cause a Panic
A Reset event (Protocol Error, Server Stop, Transport Down) will cancel the notification and move the machine to Disconnected
The NotificationComplete event will queue a async one-shot to process the returned object, moving the machine to GetOpSendObject
