public class EventProducingListIterator<T> extends EventProducingIterator<T> implements ListIterator<T>
EventProducingListIterator provides an iterator embedding the ListIterator, which fires an event when an object has been
removed. Note that one does not have to subscribe specifically to the events of the EventProducingListIterator, as the
EventProducing collection subscribes to the EventProducingListIterator's remove events and fires these again to its
subscribers.
