/*
* .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).
