Be fluent In Vert.x

With vertex you can use a fluent API. It means multiple methods calls can be chained together. It make code a little bit less verbose.

Let's try to create de response to a request in plain text ("text/plain") who return "Hello world". Be careful: the header size must be definer or chunked. Don't forget to end your request !
