title: Backbone Js - parse data issue
body: <p>I'm trying to parse data to a collection view from a json file that has number key for each group of data within it. The JSON looks like this:</p>
  
  <pre><code>{
      "0": {
          "artifact_id": "36",
          "timestamp": "2013-08-20 11:59:00",
          "modified": "2013-08-20 11:59:00",
          "text": "Why did the last one duplicate? I don't think I clicked it twice...",
          "author_desc": "",
          "object_type": "artifact",
          "comments": []
      },
      "1": {
          "artifact_id": "35",
          "timestamp": "2013-08-20 11:57:51",
          "modified": "2013-08-20 11:57:51",
          "text": "This is a new artifact for a new day.",
          "author_desc": "",
          "object_type": "artifact",
          "comments": []
      },
      "2": {
          "artifact_id": "34",
          "timestamp": "2013-08-20 11:57:50",
          "modified": "2013-08-20 11:57:50",
          "text": "This is a new artifact for a new day.",
          "author_desc": "",
          "object_type": "artifact",
          "comments": []
      }
  }
  </code></pre>
  
  <p>How do I write a model parse to take each one of the entries (0, 1, 2... etc) as each model from within the data?</p>
  
  <p>This is my collection, with the suggested addition from Casey below, however it doesn't seem to be running the parse method:</p>
  
  <pre><code>var FriendCollection = Backbone.Collection.extend({
      model: FriendModel,
      parse: function(data) {
          console.log('running parse');
          return _.map(data, _.identity);
      }
  });
  var friendCollection = new FriendCollection();
  friendCollection.reset(friendjson);
  </code></pre>
