/**
* Used to intercept and handle the responses from requests made using

* be anonymously overridden with your own response handling code.
* <p>
* Additionally, you can override the {@link #onFailure(Throwable, String)},
* {@link #onStart()}, and {@link #onFinish()} methods as required.
* <p>
* For example:
* <p>
*
* <pre>
* AsyncHttpClient client = new AsyncHttpClient();
* client.get("http://www.google.com", new AsyncHttpResponseHandler() {
* @Override
* public void onStart() {
* // Initiated the request
* }
*
* @Override
* public void onSuccess(String response) {
* // Successfully got a response
* }
*
* @Override
* public void onFailure(Throwable e, String response) {
* // Response failed :(
* }
*
* @Override
* public void onFinish() {
* // Completed the request (either success or failure)
* }
* });
