title: How do I save a nested model, and then see that nested model's key's, and values as JSON with Mongoose, MongoDB, and Node
body: <p>I'm saving an account schema, and nesting it in a User schema with Mongoose, MongoDB, and Node. 
  Save works fine, but when I look at the saved object JSON, I only see the objectId for the nested schema, and not it's keys, and values. 
  How can I save the nested schema, so that when I look at the User obj, I see the 
  all the nested schema object's keys, and values?</p>

  <p>I'd like it to look like this: </p>
