+// the notion of an "active" view vs. a "preview" tab contents view.

+// The "active" view is a container view that can be retrieved using
+// |-activeContainer|.  Its contents are meant to be managed by an external
+// class.
+//
+// The "preview" can be set using |-showPreview:| and |-hidePreview|.  When a
+// preview is set, the active view is hidden (but stays in the view hierarchy).
+// When the preview is removed, the active view is reshown.
