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.
