    - #### connect

          NetClient connect(int port,
                            String host,
                            Handler<AsyncResult<NetSocket>> connectHandler)

      Open a connection to a server at the specific `port` and `host`.

      `host` can be a valid host name or IP address. The connect is done asynchronously and on success, a `NetSocket` instance is supplied via the `connectHandler` instance

      Parameters:
        `port` - the port
        `host` - the host
      Returns:
        a reference to this, so the API can be used fluently

    - #### close

          void close()

      Close the client.

      Any sockets which have not been closed manually will be closed here. The close is asynchronous and may not complete until some time after the method has returned.
