Explanation HomeViewMediator

HomeViewMediator extends AbstractViewMediator (SkinnableComponent).

The above code, is to mediate when "ResultSignal" is dispatched.
The AbstractSignal was prior dispatched from this view only, to get server Response.

The Same signal was sent as argument "signal:SignalVO" 

Thus, we map it back to make sure about the mediated signal,
is response for what was dispatched from the same object



AbstractViewMediator initiates on addedToStage event, 
through [Mediate( event="flash.events.Event.ADDED_TO_STAGE" , properties="target",useCapture="true" )]
to achieve the PassiveView.
