     * .countDown()
     *
     * Description:
     *      Unobtrusive and easily skinable countdown jQuery plugin.
     *
     * Usage:
     *      $(element).countDown()
     *
     *      $(element) is a valid <time> or any other HTML tag containing a text representation of a date/time
     *      or duration remaining before a deadline expires.
     *      If $(element) is a <time> tag, the datetime attribute is checked first.
     *          <time datetime="2013-12-13T17:43:00">Friday, December 13th, 2013 5:43pm</time>
     *          <time>2012-12-08T14:30:00+0100</time>
     *          <time>PT01H01M15S</time>
     *          <h1>600 days, 3:59:12</h1>
     *
     *      The text representation of a date/time or duration can be:
     *      - a valid duration string:
     *          PT00M10S
     *          PT01H01M15S
     *          P2DT20H00M10S
     *      - a valid global date and time string with its timezone offset:
     *          2012-12-08T14:30:00.432+0100
     *          2012-12-08T05:30:00-0800
     *          2012-12-08T13:30Z
     *      - a valid time string:
     *          12:30
     *          12:30:39
     *          12:30:39.929
     *      - a human readable duration string:
     *          2h 0m
     *          4h 18m 3s
     *          24h00m59s
     *          600 jours, 3:59:12
     *          600 days, 3:59:12
     *      - the output of a JavaScript Date.parse() parsable string:
     *          Date.toDateString() => Sat Dec 20 2014
     *          Date.toGMTString()  => Sat, 20 Dec 2014 09:24:00 GMT
     *          Date.toUTCString()  => Sat, 20 Dec 2014 09:24:00 GMT
     *
     *      If $(element) is not a <time> tag, a new one is created and appended to $(element).
