  * - Slides that contain nested-slides are given the 'stack' class
  * 
  * version 1.2:
- * - Main container was renamed from #main to #reveal
+ * - Big changes to DOM structure:
+ *   - Previous #main wrapper is now called #reveal
+ *   - Slides were moved one level deeper, into #reveal .slides
+ *   - Controls and progress bar were moved into #reveal
+ * - All CSS is now much more explicit, rooted at #reveal, to prevent conflicts
