+// Class LLScrollableContainerView
+//
+// A view meant to encapsulate a clipped region which is
+// scrollable. It automatically takes care of pixel perfect scrolling
+// and cliipping, as well as turning the scrollbars on or off based on
+// the width and height of the view you're scrolling.
+//
+// This class is a decorator class.
