/**
 * 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' );
