In API the list of puppet classes returns results in format that is inconsistent with the rest of the API.

     "results" => {
        "apache" => [
            [ 0] {
                        "id" => 8,
                      "name" => "apache",
                "created_at" => "2014-10-08T11:39:06Z",
                "updated_at" => "2014-10-08T11:39:06Z" 
            },
            [ 1] {
                        "id" => 69,
                      "name" => "apache::confd::no_accf",
                "created_at" => "2014-10-08T11:39:07Z",
                "updated_at" => "2014-10-08T11:39:07Z" 
            },

The individual classes are nested under the module name, which makes automation dificult. I'm not sure what is the background for this deviation from usual format, but it seems that adding module name as an attribute of the class would do the job.
