   6  * Collapsible tables and divs.
   7  *
   8  * Users can create tables and nested divs which collapse either on-click or on-load,
   9  * to save space on a page, or to conceal information at first sight.  Eg:
  10  *
  11  *   <table class="wikitable collapsible collapsed"><tr>
  12  *      <th>A table header which will always be visible</th>
  13  *   </tr><tr>
  14  *      <td>A table cell which will be hidden on page-load</td>
  15  *   </tr></table>
  16  *
  17  *   <div class="collapsible collapsed">
  18  *      Content which will always be visible
  19  *      <span class="collapsible-expander">Click me!</span>
  20  *      <div>
  21  *              This content will be hidden until the span above is clicked
  22  *      </div>
  23  *   </div>
  24  *
  25  * If the user does not create a toggle-button manually, one will be created,
  26  * in the top-right header cell for tables, and at the beginning of the outer
  27  * div's content for a collapsible div.
