Example in docs does not work

Description

Executing cargo test with the provided example does not work.

$ cargo test                                                                                                                                                                        ✱
   Compiling hello-world v0.0.1 (file:///Users/willweiss/dev/rust/hello-world)
src/main.rs:21:64: 21:70 error: no method named `unwrap` found for type `iron::Response` in the current scope
src/main.rs:21     let result_body = response::extract_body_to_bytes(response.unwrap());
                                                                              ^~~~~~
error: aborting due to previous error
error: Could not compile `hello-world`.

Changing the test to read:

#[test]
fn test_hello_world() {
    let res = request::get("http://localhost:3000/hello",
                                Headers::new(),
                                &HelloWorldHandler).unwrap();
    let result_body = response::extract_body_to_bytes(res);

    assert_eq!(result_body, b"Hello, world!");
}

Fixes the issue as iron_test::response::extract_body_to_bytes takes an argument of type iron::response::Response per the docs.

Thanks in advance!
