Rugged::Tree#walk

Walk +tree+ with the given mode (either +:preorder+ or +:postorder+) and yield
to +block+ every entry in +tree+ and all its subtrees, as a +Hash+. The +block+
also takes a +root+, the relative path in the traversal, starting from the root
of the original tree.

If the +block+ returns a falsy value, that entry and its sub-entries (in the case
of a folder) will be skipped for the iteration.

If no +block+ is given, an +Iterator+ is returned instead.

  tree.walk(:postorder) { |root, entry| puts "#{root}#{entry[:name]} [#{entry[:oid]}]" }

generates:
