/**

 * value. Furthermore, in case of an <code>Object</code> field it does not
 * try to deserialize the object but stores instead the Json String to that
 * field. The deserialization has then to be handled in an extra step once the
 * final Object class information is available. 
 * @return The Gson Builder to serialize/deserialize Json messages
