/**
 * Reports a NegoState as the latest state of the protocol. The negoState is
 * abstract because the state is not something that can be handled at this place
 * in the dependency hierarchy. The "real" implementations are inside the
 * protocol.
 * <p>
 * When a protocol reports this event, it indicates that this state can be
 * logged to the loggers for output to the users (publication on the webpages
 * and reporting to parent protocols eg a tournamentrunner). Usually protocols
 * are updating this only after a session completes. There may be quite some
 * overhead triggered by emission of these events, such as rewriting files and
 * notifying end users behind websockets. Protocols MUST report this at least
 * once to report the final isFinished() state.
 * <p>
 * The logged state may be used to re-start a protocol if it crashes later in an
 * unfinished state.
