 /** A subclass of Tree.Visitor, this class defines
  *  a general tree scanner pattern. Translation proceeds recursively in

  *  for every possible kind of tree node.  To obtain a specific
  *  scanner, it suffices to override those visitor methods which
  *  do some interesting work. The scanner class itself takes care of all
  *  navigational aspects.
