This is purely a simple plugin for Robotlegs 1.5x to help your projects handle both regulardisplay list projects as well as starling display list projects. I personally have regular display list items in my starling projects (menu screens etc) and if I am using Robotlegs I want to be able to have mediators for both my regular and starling view components.
To use just swap out your mediatorMap and viewMaps in your application context:
this.mediatorMap = new RobotMediatorMap(this.contextView, starling.stage, this.injector, this.reflector);
this.viewMap = new RobotViewMap(this.contextView, starling.stage, this.injector);
Of course as you are referencing starling.stage here you will need to instantiate starling before this is done.
