/**
 * This plug-in for DataTables represents the ultimate option in extensibility
 * for sorting date / time strings correctly. It uses
 * [Moment.js](http://momentjs.com) to create automatic type detection and
 * sorting plug-ins for DataTables based on a given format. This way, DataTables
 * will automatically detect your temporal information and sort it correctly.
 *
 * For usage instructions, please see the DataTables blog
 * post that [introduces it](//datatables.net/blog/2014-12-18).
 *
 * @name Ultimate Date / Time sorting
 * @summary Sort date and time in any format using Moment.js
 * @author [Allan Jardine](//datatables.net)
 * @depends DataTables 1.10+, Moment.js 1.7+
 *
 * @example
 *    $.fn.dataTable.moment( 'HH:mm MMM D, YY' );
 *    $.fn.dataTable.moment( 'dddd, MMMM Do, YYYY' );
 *
 *    $('#example').DataTable();
