Description:
 def traverse(self, predicate=lambda i, d: True, prune=lambda i, d: False, depth=-1, branch_first=True, visit_once=False, ignore_self=1):
 """For documentation, see util.Traversable.traverse Trees are set to visit_once = False to gain more performance in the traversal"""

        return super(Tree, self).traverse(predicate, prune, depth, branch_first, visit_once, ignore_self)
