/**
 * This function will restore the order in which data was read into a DataTable
 * (for example from an HTML source). Although you can set aaSorting to be an
 * empty array (`[ ]`) in order to prevent sorting during initialisation, it can
 * sometimes be useful to restore the original order after sorting has already
 * occurred - which is exactly what this function does.
 *
 *  @name fnSortNeutral
 *  @summary Change ordering of the table to its data load order
 *  @author [Allan Jardine](http://sprymedia.co.uk)
 *
 *  @example
 *    $(document).ready(function() {
 *        var table = $('#example').dataTable();
 *         
 *        // Sort in the order that was originally in the HTML
 *        table.fnSortNeutral();
 *    } );
