19/**
20 * Expands text to fill up the entire width of its parent (or at least as much
21 * as possible). It does this in 2 ways. First, it finds the largest font-size
22 * for the text that can still fits on one line. If there is still some space
23 * left to fill, it will increase the gap between the words as well to fill the
24 * remaining space.
25 *
26 * For example, say we wanted to make the following title, "Sprockets and 
27 * Widgets" take up as much of the full 400px of width as possible:
28 *
29 *  <h1 style="width: 400px">Sprockets and Widgets</h1>
30 *  <script>
31 *    $("h1").contents().fillWidth();
32 *  </script>
