Provide trie traversal functions (feature request)

[pombredanne]

It would be great to have some functions similar in logic to os.walk e.g. top down, breadth first and bottom up depth first "postorder" traversal of the trie.

traverse can be used to implement breadth-first traversal. As a matter of fact it can be used to do whatever one wishes. Having said that, post-order should be rather simple to add to iteritems so I’ll go ahead and do that (not sure when though).

Thanks! 👍

Post-order is now available in experimental branch.
