+/**
+ * This plug-in provides the ability to sort columns that contains time
+ * information in the most common formats used. It will automatically detect
+ * those date types.
+ *
+ *  @name Time (dd/mm/YY)
+ *  @summary Sort Times in the formats: `hh:mm, hh:mm:ss, hh:mm tt, hh:mm:ss tt`
+ *    e.g. '22:50, 22:50:40, 10:50 pm, 10:50:40 pm' 
+ *    am and pm are not case sensitive. white space is not compulsory
+ *  @author David Stoneham
+ *
+ *  @example
+ *    $('#example').dataTable( {
+ *       columnDefs: [
+ *         { type: 'time-uni', targets: 0 }
+ *       ]
+ *    } );
