- * This test exists to insure that didLayoutSubviews is always called immediately after layoutSubviews for a VC:View
- * pair. In Catalyst we have multiple levels of ViewController containment, and we rely on this ordering
- * to insure that layoutGuides are set on RKViewControllers before Views further down in the hierarchy have
- * their layoutSubviews called (and need to use the aforementioned layoutGuides)
