   * 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.
