?/**
 * This sorting plug-in will sort, in calendar order, data which
 * is in the format "MMM yyyy" or "MMMM yyyy". Inspired by forum discussion:
 * http://datatables.net/forums/discussion/1242/sorting-dates-with-only-month-and-year
 *
 * 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 (MMM yyyy) or (MMMM yyyy)
 *  @anchor Sort dates in the format `MMM yyyy` or `MMMM yyyy`

 *    $('#example').DataTable( {
 *       columnDefs: [
 *         { type: 'stringMonthYear', targets: 0 }
 *       ]
 *    } );
