* Simple implementation of {@link AsyncHttpClient} and it's related builders ({@link com.ning.http.client.AsyncHttpClientConfig},
* {@link Realm}, {@link com.ning.http.client.ProxyServer} and {@link com.ning.http.client.AsyncHandler}. You can
* build powerful application by just using this class.
*
* This class rely on {@link BodyGenerator} and {@link BodyConsumer} for handling the request and response body. No
* {@link AsyncHandler} are required. As simple as:
*
* SimpleAsyncHttpClient client = new SimpleAsyncHttpClient.Builder()
* .setIdleConnectionInPoolTimeout(100)
* .setMaximumConnectionsTotal(50)
* .setRequestTimeout(5 * 60 * 1000)
* .setUrl(getTargetUrl())
* .setHeader("Content-Type", "text/html").build();
*
* StringBuilder s = new StringBuilder();
* Future future = client.post(new InputStreamBodyGenerator(new ByteArrayInputStream(MY_MESSAGE.getBytes())), new AppendableBodyConsumer(s));
*
* or
*
* public void ByteArrayOutputStreamBodyConsumerTest() throws Throwable {
*
* SimpleAsyncHttpClient client = new SimpleAsyncHttpClient.Builder()
* .setUrl(getTargetUrl())
* .build();
*
* ByteArrayOutputStream o = new ByteArrayOutputStream(10);
* Future future = client.post(new FileodyGenerator(myFile), new OutputStreamBodyConsumer(o));
