Adds first half of the JSON Library Construction tutorial for RWH ch. 05

I'm increasingly finding Real World Haskell to be an extremely poor resource. It has outdated instructions for compiling and it's riddled with too many errors for a good-faith learner to make sense of what code goes where. It poorly motivates design choices and functions. I'm at a complete loss as to why this book is so popular among python programmers.
