/**
* Search through a table looking for a given string (optionally the search
* can be restricted to a single column). The return value is an array with
* 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 table = $('#example').dataTable();
*
* var a = table.fnFindCellRowIndexes( '1.7' ); // Search all columns
*
* var b = table.fnFindCellRowIndexes( '1.7', 3 ); // Search only column 3
* } );
