In the implementation of NotifierToKeyToListenersSetMap.addListener
        public void addListener(EObject notifier, Object key, Object listener) {
            Map keys = (Map) listenersMap.get(notifier);
            if (keys == null) {
                keys = new HashMap();
                listenersMap.put(notifier, keys);
            }
            Set listenersSet = (Set) keys.get(key);
            if (listenersSet == null) {
                listenersSet = new HashSet();
                keys.put(key, listenersSet);
            }
            listenersSet.add(listener);
        }

By using initial size of 4 for both HashMap and HashSet, reduces the retained size of memory in one scenario from 
	3,138,288 to 2,416,736 bytes.
