/**
* SystemRunner is used internally by the renderers as an efficient way for systems to
* be notified about what the renderer is up to during the rendering phase.
*
* ```
* import { SystemRunner } from 'pixi.js';
*
* const myObject = {
* loaded: new SystemRunner('loaded')
* }
*
* const listener = {
* loaded: function(){
* // thin
* }
* }
*
* myObject.loaded.add(listener);
*
* myObject.loaded.emit();
* ```
*
* Or for handling calling the same function on many items
* ```
* import { SystemRunner } from 'pixi.js';
*
* const myGame = {
* update: new SystemRunner('update')
* }
*
* const gameObject = {
* update: function(time){
* // update my gamey state
* }
* }
*
* myGame.update.add(gameObject);
*
* myGame.update.emit(time);
* ```
