   6  * @fileoverview A JavaScript class for walking the leaf nodes of the dom.
   7  * This is a bare class that tries to limit dependencies. It should only be used
   8  * when traversal of the leaf nodes is required (e.g. by other walkers), but
   9  * no other walker functionality (such as being able to describe the position).
  10  * It should not be used for user-visible navigation.
