a finale

Let's first put it in place ready for testing:

function get_pic() {
  clear();
  if (g_count<g_questions) {
    ...
  } else {
    finale();
  }
}

and clearly we'll need to add this display to our quiz.html.

<html>
...
  </div>
  <div id='end'>
    <script>strip();</script>
  </div>
  <script>setup();</script>
</body>
</html>
