/**
 * This sorting plug-in for DataTables will correctly sort data in date time or date

 * date and time:`dd.mm.YYYY HH:mm`
 * just date:`dd.mm.YYYY`.
 *
 * Please note that this plug-in is **deprecated*. The
 * [datetime](//datatables.net/blog/2014-12-18) plug-in provides enhanced
 * functionality and flexibility.
 *
 *  @name Date (dd.mm.YYYY) or date and time (dd.mm.YYYY HH:mm)
 *  @summary Sort date / time in the format `dd.mm.YYYY HH:mm` or `dd.mm.YYYY`.
