title: Ember-CLI: Initializers and Initializer subclass
body: <p>Currently, in Ember-CLI an Initializer is defined like so:</p>
  
  <pre><code>// app/initializers/observation.js
  export default {
    name: 'observation',
    initialize: function() {
      // code
    }
  };
  </code></pre>
  
  <p>in this case, how would I define a sub-class of that Initializer... is the following code correct?</p>
  
  <pre><code>// app/initializers/close-observation.js
  export default Ember.Observation.extend{
    newProperty: 1,
    otherProperties: 2
  };
  </code></pre>
