title: RapidJSON get member name of Value
body: <p>Wondering if it's possible to extract the name of a <code>rapidjson::Value</code> directly from it. </p>
  
  <p>For instance, assume we have the following JSON data:</p>
  
  <pre><code>{
      "name":
      [
          { /*some data*/ },
          { /*some more data*/ }
      ]
  }
  </code></pre>
  
  <p>And I retrieve the "name" array from it:</p>
  
  <pre><code>rapidjson::Value&amp; myJSONArray = document["name"];
  </code></pre>
  
  <p>Can I retrieve "name" back from that <code>Value</code>? Something like this:</p>
  
  <pre><code>std::string memberName = myJSONArray.GetMemberName(); // returns "name"
  </code></pre>
