I have a GEF editor with several actions in the ContextMenu. Please show me

1. In your action, create a Request that is sent to the relevant EditParts.
2. On the EditPart, install an EditPolicy which handles the Request by
creating a Command.
3. Execute the Command on the CommandStack. Do not call Cammand.execute()
directly.
