Description:

I'm trying to use this package with Backpack. Backpack is requesting that method:

 public function getDoctrineConnection()

    {

        if (is_null($this->doctrineConnection)) {

            $driver = $this->getDoctrineDriver();
 ...

As far as I understood, this is an issue with the fact that now Backpack uses the doctrine abstraction to access the db. I'm happy to work on it, I'm just unsure on where I should start, because there seems to be no way to get hold of the driver object in mongodb.
