This component forwards on any messages it receives that it has not seen before.
Lines entered into this setup will only be duplicated on screen the first time they are entered:
pipeline( ConsoleReader(), UnseenOnly(), ConsoleEchoer() ).run()
UnseenOnly() -> new UnseenOnly component.
Send items to the "inbox" inbox. Any items not "seen" already will be forwarded out of the "outbox" outbox. Send the same thing two or more times and it will only be sent on the first time.

Please leave you feedback here in reply to the documentation thread in the Kamaelia blog.
