Events #
An event system allows to be notified when the SDK status changes. These events are issued by the Kuzzle SDK object.
Subscription to these events is possible by specifying callbacks that will be executed when a specific event is issued by the SDK instance.
These callbacks can be added by the method addListener.
Note: listeners are called in the order of their insertion.
