PHPSQLCreator error when FROM clause is absent

Some SQL queries do not have a table / from clause. The parser works fine, the 
creator assumes the FROM clause will always be present.

$parser = new PHPSQLParser;
$parsed = $parser->parse('SELECT NOW()');
$creator = new PHPSQLCreator();
print $creator->create($parsed);

What is the expected output? What do you see instead?
Expected "SELECT NOW()", Got undefined index 'FROM'

Simple fix to change processSelectStatement:71
from:
$sql = $this->processSELECT($parsed['SELECT']) . " " . 
$this->processFROM($parsed['FROM']);
to:
            $sql = $this->processSELECT($parsed['SELECT']);
            if (isset($parsed['FROM'])) {
                $sql .= " " . $this->processFROM($parsed['FROM']);
            }
