In all reality we could be building our objects and its dependencies, object graph, without any configuration just plain location and implicit conventions. This is great but not very flexible for refactoring, so let's do the best practice of defining a mapping or an alias to a real object.
We do this by creating a WireBox configuration binder
wirebox.system.ioc.config.Binder, which is a simple CFC that defines the way WireBox behaves and defines object mappings. This binder is then used to initialize WireBox so it has knowledge of these mappings and our settings.
The Binder is also the way you configure WireBox for operation.
