-/**
- * A VirtualUniverse object is the top-level container for all scene
- * graphs.  A virtual universe consists of a set of Locale objects,
- * each of which has a high-resolution position within the virtual
- * universe.  An application or applet may have more than one
- * VirtualUniverse objects, but many applications will need only one.
- * Virtual universes are separate entities in that no node object may
- * exist in more than one virtual universe at any one time. Likewise,
- * the objects in one virtual universe are not visible in, nor do they
- * interact with objects in, any other virtual universe.
- * <p>
- * A VirtualUniverse object defines methods to enumerate its Locale
- * objects and to remove them from the virtual universe.
- *
- * <p>
