/**
 * A {@link HttpMessageConverter} that can be used with spring that will do the internal conversion
 * using a {@link JsonCerealEngine}. When configured, this will convert all {@link ResponseBody} and
 * {@link RequestBody} objects that use the content type of "application/json".
 *
 * 
 * To use this in a spring web application, simply add this code to your
 * app-context.xml:
 * 
 *
 *  *   <mvc:annotation-driven>
 *     <mvc:message-converters register-defaults="false">
 *       <bean class="com.comcast.tvx.megahttp.spring.JsonCerealHttpMessageConverter" />
 *     </mvc:message-converters>
 *   </mvc:annotation-driven>
 * 
 *
 * 
 * To configure to use an existing (and shared) {@link JsonCerealEngine} named "jsonEngine", use the
 * following configuration pattern:
 * 
 *
 *  *   <mvc:annotation-driven>
 *     <mvc:message-converters register-defaults="false">
 *       <bean class="com.comcast.tvx.megahttp.spring.JsonCerealHttpMessageConverter">
 *         <constructor-arg index="0" ref="jsonEngine" />
 *       </bean>
 *     </mvc:message-converters>
 *   </mvc:annotation-driven>
 *
