apigility and config file

[michalbundyra]

Hi,
when create new api from the interface it was a nice think to create the invoke of the resource factory in this way:

public function __invoke($services)
{
return new MyResouceResource($services);
}

and inside the resouce file a constructor like this:

public function __construct($services)
{
$config = $services->get('Config');
}

so we can manage the config keys and the database setting and adapter.
Thanks
