Support for expressions in ORDER BY clause

This works fine:
SELECT f FROM t ORDER BY f-0.0

But this fails on create:
SELECT f FROM t ORDER BY (f-0.0)

This isn't a problem for me since the first statement works fine, just 
something I noticed.

To reproduce, I wrote this script:

require_once "src/PHPSQLParser/PHPSQLParser.php";
require_once "src/PHPSQLParser/PHPSQLCreator.php";
$parser = new PHPSQLParser\PHPSQLParser();
$creator = new PHPSQLParser\PHPSQLCreator();
$x = $parser->parse("SELECT f FROM t ORDER BY (f-0.0)");
var_dump($creator->create($x));

Stack trace:

'PHPSQLParser\exceptions\UnableToCreateSQLException' with message 'unknown

This is testing against the master branch of the git repository
