/**
 * Use this BeanDefinitionParser when you need a "wrapper" element for an ObjectFactory.
 * For example, suppose we have the following class:
 * 
 *   class Car
 *   {
 *     private ObjectFactory<Wheel> wheel;
 *   }
 * 
 * The following registration in the namespace:
 *
 *   registerBeanDefinitionParser("wheel", new ObjectFactoryWrapper("wheel"));
 * 
 * would allow a config such as:
 * 
 *   <car>
 *     <wheel>
 *       <prototype-object class="com.wheelsrus.BigWheel">
 *         <properties>
 *           <spring:property name="tire" value="goodyear"/>
 *           <spring:property name="diameter" value="35R"/>
 *         </properties>
 *       </prototype-object>
 *     </wheel>
 *   </car>
