// The JavaScript for the buttons at the bottom of the left-hand frame follows.  
   // These functions expand all nodes in the tree, collapse all nodes in the tree,
   // open a specific node in the tree, or load a particular document in the 
   // right-hand frame.
   //
   // The buttons in this demo are in a separate frame both from the actual tree 
   // and from the actual content.  If you want to include the buttons in the same 
   // frame as the tree, or in the same frame as the documents, move these 
   // functions to the appropriate file.  For example, in the case of this example,
   // if you want to display the buttons on the same frame as the tree, move these 
   // functions to the demoFuncs.html file.  If you move these functions, you must
   // update the DOM paths used to access the functions and used by the functions 
   // themselves.

   // The expandTree function expands all children nodes for the specified node. 
   // The specified node must be a folder node. 
   // When the specified node is the root node, this function opens all nodes in 
   // the tree.  When the specified is not the root node, only the children of the 
   // specified node are opened.
   // Note that for some very large trees, the browser may time out when this 
   // function is used.
