/**

 <code>TreeWalker</code> objects are used to navigate a document
 tree or subtree using the view of the document defined by its
 <code>whatToShow</code> flags and any filters that are defined
 for the <code>TreeWalker</code> . Any function which performs
 navigation using a <code>TreeWalker</code> will automatically
 support any view defined by a <code>TreeWalker</code> .
  Omitting nodes from the logical view of a subtree can result in a
 structure that is substantially different from the same subtree in
 the complete, unfiltered document. Nodes that are siblings in the
 TreeWalker view may be children of different, widely separated
 nodes in the original view. For instance, consider a Filter that
 skips all nodes except for Text nodes and the root node of a
 document. In the logical view that results, all text nodes will be
 siblings and appear as direct children of the root node, no matter
 how deeply nested the structure of the original document.
