/**
 * A cxf feature whose role is to call the list of actual features from the FeatureIntegrationFactory.
 * 
 * Note: we can only pass a feature to the service methods using a cxf annotation, and not an external
 * configuration file (since that requires integrating spring with the application server running cxf).
 * Since the annotation requires a hardcoded feature class name, we need a class like this to allow for
 * runtime management of features to be added.
