title: Mapping an object to JSON using RKObjectMapping
body: <p>I'm a bit new to RKObjectMapping, and I'm having some trouble figuring this out.</p>
  
  <p>I have a class which has an array of objects called myObjects. This type of object already has an object mapping in its class. I want to map to the following kind of JSON object:</p>
  
  <pre><code>{
    "myObjects": [...]
  }
  </code></pre>
  
  <p>where the JSON array contains JSON objects determined by myObjects and the object mapping I am already given.</p>
  
  <p>How would I go about making an object mapping to do this?</p>
