  the state of a room's root. At its root, a room consists of and
  is organized into a set of CollectionNodes. RootCollectionNode allows the 
  developer to determine this set, using collectionNames, as well as the 
  <code>NODE_CREATE</code> and <code>NODE_DELETE</code> events. 
  <p>
  Note that only one RootCollectionNode may be present in an application, 
  and that <code>subscribe()</code> must be called on the RootCollectionNode 
  before use.
