 9  * This is a simple abstraction over top an HTTP response. This

13  *
14  * ```php
15  * $response = new Docolight\Http\JsonResponse(new Docolight\Http\Headers());
16  *
17  * // Or you can resolve via factory
18  * // $response = with(new Docolight\Http\ResponseFactory())->produce('json');
19  *
20  * // Move even shorter way
21  * // $response = container('response')->produce('json');
22  *
23  * // Set your header
24  * $response->headers->set('Foo', 'Bar');
25  *
26  * // Set your response status
27  * $response->setStatus(202);
28  *
29  * // Set your response body
30  * $response->setBody(new Docolight\Support\Fluent(array('my_json_index' => 'my_json_value')));
31  *
32  * // Send your response to client
33  * $response->send();
34  *
35  * // In shorter way
36  * // response(
37  * //    'json',
38  * //    200,
39  * //    new Docolight\Support\Fluent(array('my_json_index' => 'my_json_value')),
