Notifier class
A notifier emits events intended to be used for implementing client-side notifications.
A notifier will emit an updated event whenever there is a new message
posted in any of the rooms of the connected user (of course, excluding
messages authored by the latter). In case the websocket connection
temporarily drops, upon reconnecting the notifier will emit events for the
messages missed while the client was disconnected.
List of events

The attached event listeners are called with an ErrorEvent instance.ready→ Fired at most once, when the connection to the server is first established. The attached event listeners are called with a NotifierReadyEvent instance.updated→ Fired when there is a new message posted in any of the rooms that the connected user has access to. The attached event listeners are called with a NotifierUpdatedEvent instance.
