+/**
+ * Data can often be a complicated mix of numbers and letters (file names
+ * are a common example) and sorting them in a natural manner is quite a
+ * difficult problem.
+ * 
+ * Fortunately a deal of work has already been done in this area by other
+ * authors - the following plug-in uses the [naturalSort() function by Jim
+ * Palmer](http://www.overset.com/2008/09/01/javascript-natural-sort-algorithm-with-unicode-support) to provide natural sorting in DataTables.

+ *  @name Natural sorting
+ *  @summary Sort data with a mix of numbers and letters _naturally_.
+ *  @author [Jim Palmer](http://www.overset.com/2008/09/01/javascript-natural-sort-algorithm-with-unicode-support)

+ *  @example
+ *    $('#example').dataTable( {
+ *       columnDefs: [
