Just noting that this seems (still) wierd :) https://github.com/dantleech/DoctrinePHPCRBundle/blob/intializer_and_fixtures_2/Command/DoctrineCommandHelper.php#L40

This should be simply:

````
$this->getHelper('phpcr')->setSession($input->getOption('session')
````

and then maybe these commands shouldn't extend the base commands but wrap them instead, allowing us to extend a common base class for phpcr-odm commands.
