/**
 * This annotation can be used to mark a method parameter to be an url variable.
 * This annotation is optional, because method parameters which are not
 * annotated with any annotation or not correspond to the request entity,
 * implicitly interpreted as url variables. However with this annotation you can
 * explicitly mark them. Also, with the annotation value, you can add another
 * name to the url variable. If an url variable method parameter does not have
 * the {@link Path} annotation, or the annotation value is not specified, the
 * method parameter name will be used as the url variable name. The url in the
 * {@link Get} etc. annotation must contain an url variable, which the
 * corresponding method variable will be substituted into.
 *
 * 
 *
 * Example :
 *
 *  * @Rest(converters = MappingJacksonHttpMessageConverter.class)
 * public interface MyRestClient {
 *
 * 	@Get("/event/{id}")
 * 	Event getEvent(String id);
 *
 * 	@Get("/event/{id}")
 * 	Event getEventWithPathAnnotation(@Path String id);
 *
 * 	@Get("/event/{id}")
 * 	Event getEventWithPathAnnotationValue(@Path("id") String identifier);
 * }
 * 
 *
 * 
 *
 * @see Rest
