I wanted to create an easy-to-use helper class that can deal with async process state changes in AS3.
A SignalResponder allows you to easily respond to start, progress, success and failure signals.
It’s meant to be a versatile class, that can be used in many different ways, allowing to use them
in any way you see fit.
