 * You can also bind to the "searchEnd.simpleFAQ" event to be notified
 * when the search is completed. This event is fired in parallel with 
 * "sort.simpleFAQ", so you will get both events. The second argument 
 * to the handler will be an array of the (sorted) result nodes.
    $('#faqs').bind('searchEnd.simpleFAQ', function(jQEvent, results) {
      // do something
    });
 * 
 * TODO:
 *   Full testing suite
 * 
 * REVISIONS:
 *   0.1 Initial release
 *   0.2 Added speed option (thanks to Ferenc Radius)
 *       Minor other changes (size, comments/notes)
 *   0.3 Added caseSensitive option for searches
 *       Added list of words to ignore when searching/scoring
 *       Added "searchStart" and "searchEnd" events
 *       Added more classes to FAQs found by searching
 *   0.4 Fixed issue with class on shown answers
 *       NOTE: The answer div no longer has the simpleFAQShowing class added!
 *             In your CSS you will need to use "li.simpleFAQShowing .answer".
 *   0.5 Fixed bug where nodeTypes (usually "li") within a FAQ were selected as FAQs
 *         (In other words, you had a FAQ that was an LI, and then an LI inside that.)
 *       Added audit for single root node in jQuery chain, otherwise we kind of break.
 *   0.6 Added direct FAQ jumping using URL anchors (thanks to Ian G. for the idea and starting code)
 *   0.7 Minor bug fix (leftover console statement) and file size reduction
