+/*
+ * Adds a new sorting option to dataTables called <code>datetime-us</code>. Also
+ * includes a type detection plug-in. Matches and sorts date / time strings in
+ * the format: <code>(m)m/(d)d/(yy)yy (h)h/m(m) (am|pm)</code>. For example:
+ *   <ul>
+ *      <li>1/1/13 1:4 pm</li>
+ *      <li>01/01/2013 01:04 PM</li>
+ *      <li>1/1/2013 1:04 Pm</li>
+ *   </ul>
+ *
+ *  @name Date / time - US
+ *  @anchor datetime_us
