+ * ASNavigationController
+ *
+ * @discussion ASNavigationController is a drop in replacement for UINavigationController
+ * which improves memory efficiency by implementing the @c ASManagesChildVisibilityDepth protocol.
+ * You can use ASNavigationController with regular UIViewControllers, as well as ASViewControllers. 
+ * It is safe to subclass or use even where AsyncDisplayKit is not adopted.
+ *
+ * @see ASManagesChildVisibilityDepth
