/**
* This plug-in for DataTables represents the ultimate option in extensibility
* for sorting date / time strings correctly. It uses
* [luxon](https://moment.github.io/luxon/) 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 luxon
* @author [Allan Jardine](//datatables.net)
* @depends DataTables 1.10+, luxon.js 1.0+
*
* @example
* $.fn.dataTable.luxon( 'HH:mm MMM d, yy' );
* $.fn.dataTable.luxon( 'EEE, MMMM Do, yyyy' );
*
* $('#example').DataTable();
