-.PP
-Walks the tree starting from root, applying handler to each node.
-Nodes that can have children are visited twice, once on the way in
-and once on the way out.  handler is a function that takes a node
-pointer, a cmark_event_type,
-and a pointer to a state structure that can be consulted and
-updated by the handler.  The handler should return 1 on success,
-0 on failure.  cmark_walk returns 1 if it traversed the entire
-tree, 0 if it quit early in response to a 0 status from the
-handler.
