       * 
       * In here you can listen for Scene events and set-up whatever you need for this plugin to run.
       * Here are the Scene events you can listen to:
       * 
       * start
       * ready
       * preupdate
       * update
       * postupdate
       * resize

       * sleep
       * wake

       * transitionstart
       * transitioncomplete
       * transitionout
       * shutdown
       * destroy
       * 
       * At the very least you should offer a destroy handler for when the Scene closes down, i.e:
       *
       * ```javascript
       * var eventEmitter = this.systems.events;
       * eventEmitter.once('destroy', this.sceneDestroy, this);
