Simple and similar with `event-emitter`.

 - `once(eventName: string, callback: Function)`: listen a event only once.
 - `fire(eventName: string, ...parameters: any[])`: emit / trigger an event with parameters.
 - `off(eventName?: string, callback?: Function)`: unsubscribe an event.

## Used

- Events subscribe and dispatcher.
 - `Cross-component communication` for React / Vue / Angular.
 - System event mechanism.
