#8 Incapable to handle more than one class correctly

[Alex Simov]

Having mapping for two or more classes (i.e. 'class1'=>"SELECT ....", 'class2'=>"SELECT ...." ,'class3'=> .....) I receive triplified data only for the first one. Digging into the code, I discovered that the reason is not releasing the result handle ($res) from any previous evaluation, so any subsequent query evaluations result in empty result.
Inserting an additional line '$res = null;' at row 196 in index.php (preceding 'if($res=$this->dbQuery($query)) {') fixed the issue. I have to admit I use php for a first time so this might be not the best solution but for me it works well.
I use triplify 0.8 (though it is printing in the result triple set '0.7.1')
