The main entry point of a :mod:`jcn`-based application. :meth:`run`
        sets up the terminal and then runs then event loop, continually
        responding to user input and drawing UI element to the screen when
        required.

        Specifically, :mod:`jcn` applications run the terminal full-screen and
        with the cursor hidden, and set :attr:`sys.stdin` to unbuffered and
        non-blocking so that we can respond immediately to any keystrokes from
        the user. We also correctly handle being suspended (:kbd:`Control-z`,
        SIGTSTP) and resumed, and the terminal window being resized.

        We run :mod:`asyncio` event loop inside context managers that will
        handle exceptions gracefully and return the terminal to the previous
        state before exiting. Aren't we nice ;-)
