 *
 * A Notifier is notified when the index in the queue viewed as array of some
 * data item has been changed, this gives the Notifier object the ability to
 * update its value of the index for that data item. As an example, in the
 * search engine, the WebQueueBundle class implements Notifier. Web queue
 * bundles store url together with their weights and allow one to get out the
 * url of highest weight. This is implemented by storing in a PriorityQueue
 * keys consisting of hashes of urls (as fixed length) and values consisting of
 * the weight. Then in a web archive the url and its index in the priority
 * queue is stored. When the index in the queue changes, the WebQueueBundle's
 * notify method is called to adjust the index that is stored in the web
 * archive.
