ObjectManager - A class for adding a large number of objects to the map
without needing to create placemarks individually.
Objects added in ObjectManager are in the ObjectManager.objects collection.
The clusters formed from the added placemarks are added to the ObjectManager.clusters collection.
These collections have managers that control balloons and hints (ObjectManager.objects.balloon, ObjectManager.clusters.hint).
