Simplest Aeson json parsing and generation example
{-# LANGUAGE OverloadedStrings #-}
-- This is a very simple example of parsing and generating json with Aeson,
-- by a haskell newbie and intended for newbies.
--
-- This almost certainly contains a number of bad practices. It works for
-- me and hopefully will get you started.
--
-- I couldn't find a stand-alone example of Aeson usage and found it tricky to
-- get going. For example, if you don't realize to enable the language extension
