/**
 * 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 the Javascript `localeCompare` method is now widely supported
 * and provides a natural sorting method we can use with DataTables.
 *
 *  @name Natural sorting
 *  @summary Sort data with a mix of numbers and letters _naturally_.
 *  @author Allan Jardine
 *  @requires DataTables 2+
 *
 *  @example
 *   // Natural sorting
 *   new DataTable('#myTable',
 *       columnDefs: [
 *           { type: 'natural', target: 0 }
 *       ]
 *   } );
 *
 *  @example
 *   // Html can be stripped from sorting by using 'natural-nohtml' such as
 *   new DataTable('#myTable',
 *       columnDefs: [
 *    	     { type: 'natural-nohtml', target: 0 }
 *       ]
 *    } );
 *
 *  @example
 *   // Case insensitive natural sorting
 *   new DataTable('#myTable',
 *       columnDefs: [
 *    	     { type: 'natural-ci', target: 0 }
 *       ]
 *    } );
