title: How to fetch dictionaries within dictionaries in a JSON string?
body: <p>Using the Facebook Graph API I want to get location data.</p>
  
  <pre><code>{
     "name": "Joe Smith",
     "link": "http://www.facebook.com/joey",
     "location": {
        "id": "105590706140862",
        "name": "Fairfield, Iowa"
     }
  }
  </code></pre>
  
  <p>I can take this object and do things like <code>object["name"]</code> to get the name Joe Smith.  But how do I get the name "Fairfield, Iowa"?</p>
