   8  * This widget has the core smarts for showing a single notice: what to display,
   9  * where, and under which circumstances. Its key method is show(); this is a recipe
  10  * that calls all the other show*() methods to build up a single notice. The
  11  * ProfileNoticeListItem subclass, for example, overrides showAuthor() to skip
  12  * author info (since that's implicit by the data in the page).
