title: Getting value from json-spirit
body: <p>I'm using the Json-Spirit library, however i'm unsure how to read value from an object, without iterating over each of the name-value pairs.</p>
  
  <p>If i have an object such that:  </p>
  
  <pre><code>{
      "boids":
      {
          "width": 10,
          "count": 5,
          "maxSpeedMin": 2,
          "maxSpeedMax": 80,
          "maxForceMin": 0.5,
          "maxForceMax": 40
      }
  }
  </code></pre>
  
  <p>How can I access, for example, the <code>width</code> value by name?</p>
