/*
* Adds a new sorting option to dataTables called `date-dd-mmm-yyyy`. Also
* includes a type detection plug-in. Matches and sorts date strings in
* the format: `dd/mmm/yyyy`. For example:
*
* * 02-FEB-1978
* * 17-MAY-2013
* * 31-JAN-2014
*
* 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-mmm-yyyy)
* @summary Sort dates in the format `dd-mmm-yyyy`
* @author [Jeromy French](http://www.appliedinter.net/jeromy_works/)
* @deprecated
*
* @example
* $('#example').dataTable( {
* columnDefs: [
* { type: 'date-dd-mmm-yyyy', targets: 0 }
* ]
* } );
