/**
 * Search through a table looking for a given string (optionally the search

 * the data indexes (from DataTables' internal data store) for any rows which
 * match.
 *
 *  @name fnFindCellRowIndexes
 *  @summary Search for data, returning row indexes
 *  @author [Allan Jardine](http://sprymedia.co.uk)
 *
 *  @param {string} sSearch Data to search for
 *  @param {integer} [iColumn=null] Limit search to this column
 *  @returns {array} Array of row indexes with this data
 *
 *  @example
 *    $(document).ready(function() {

 * 
 *        var a = table.fnFindCellRowIndexes( '1.7' ); // Search all columns
