cgroup missing related model

[Tim Black]

The current model object configuration causes the following warning in the JavaScript console:

Relation=
child
; no model, key or relatedModel (function (){ parent.apply(this, arguments); }, "cgroup", undefined) backbone-relational.js:500

It appears the fix here is to define the relations correctly on the model when calling Backbone.RelationalModel.extend()

I think this is the fix: http://stackoverflow.com/a/23173497
