title: Serializing a scala object into a JSon String using lift-json
body: <p>I am wondering, would you please let me know how can I use lift-json to serialize a simple bean class into json string (I'm using v2.0-M1).
  I tried:</p>
  <pre><code>val r = JsonDSL.pretty(JsonAST.render(myBean))
  </code></pre>
  <p>and I am getting</p>
  <pre><code>[error]  found   : MyBean
  [error]  required: net.liftweb.json.JsonAST.JValue
  </code></pre>
