/**
 * An interface that can be implemented to create a {@link org.hamcrest.Matcher} based on the contents of a response. For example imagine that a
 * resource "/x" returns the following JSON document:
 *  * {
 *      "userId" : "my-id",
 *      "href" : "http://localhost:8080/my-id"
 * }
 * 
 * you can then verify the href using:
 *  * get("/x").then().body("href", new ResponseAwareMatcher() {
 *                       public Matcher matcher(Response response) {
 *                           return equalTo("http://localhost:8080/" + response.path("userId"));
 *                       }
 *                  });
 * 
 * ResponseAwareMatchers are also composable with other ResponseAwareMatchers and other Hamcrest matchers.
 * 
 * Note that you can also use some of the predefined methods in {@link RestAssuredMatchers}.
 * 
 *
 * @param  The type of the response.
