-/** Class to handle responding to clients.
- *
- * This is an abstract base class to fully abstract the details of client
- * communication from the internals of the engine.
- *
- * Note that this class only handles sending responses to commands from
- * clients, (ie OK or an error), <b>not</b> notifications (ie new node,
- * disconnection) - that's what ClientInterface is for. If a command is
- * a request, the ClientKey of the Responder can be used to find the
- * ClientInterface which should receive the response.
- *
- * ClientInterface and Responder are seperate because responding might not
- * actually get exposed to the client interface (eg in simulated blocking
- * interfaces that wait for responses before returning).
- *
- * Note for messages that have a "response" and some broadcasted effect
- * (eg setting a port value) the "response" MUST be sent first since Responder
- * is responsible for controlling whether the client wishes to receive the
- * notification.
