/**

 * Maintenance of web-sites can often cause unexpected headaches, particularly

 * if the hardcoded index of an array (the columns in a DataTables instance)

 * needs to change due to an added or removed column. This plug-in function

 * will match a given string to the title of a column in the table and return

 * the column index, helping to overcome this problem.

 *

 *  @name fnGetColumnIndex

 *  @summary Get the column index by searching the column titles

 *  @author [Michael Ross](http://www.rosstechassociates.com/)

 *

 *  @param {string} sCol Column title to search for

 *  @returns {integer} Column index, or -1 if not found

 *

 *  @example

 *    var table = $('#example').dataTable();

 *    table.fnGetColumnIndex( 'Browser' );
