 * A ResourceList is a subscriber. It can be added to a notifiers
 * list of subscribers and has a updateNotifyBody-method just like
 * all other Subscribers, but a ResourceList also has a set of 
 * subscribers on it's own, and in that sense acts as a Notifier.
 * It would be suitable to convert at least  the Subscriber class into
 * an Interface, so that this class will be more natural.
