Namespacing issue for helper functions #10

Hi I'm trying to call cl_image_upload_tag() in a Symfony2 controller. Because this is a helper function and not part of the Cloudinary or Uploader classes, I can't seem to call the function in a civilized php way.

$cloud_form = \cl_image_upload_tag('image_id', array("callback" => $this->get("router")->generate("cloudinary_callback")));

In Sf2 I need to handle the logic in a controller and then echo out the result in Twig: {{ cloud_form|raw }}

People with more ability than me say that we need to improve the composer instructions for the Cloudinary code set.
