724<p itemprop="articleBody">Utility methods for iterating over tree structured items.
725
726 Since the view hierarchy is a tree - having a method of iterating over its contents
727 is useful.
728
729 This is generalized for any object which can display tree like qualities - but this
730 generalization was done for testability concerns (since creating View hierarchies is a pain).
731
732 Only public methods of this utility class are considered public API of the test framework.
