Add three READMEs

[SamuelSchlesinger]

There should be three READMEs:

• [x] One for the entire repo, explaining the structural design decisions, the choice of servant as the framework, how to spin this up locally, and how I deploy it to AWS (which I have not yet done, my crappy site is still up there).
• [x] Another for the api package, explaining the API itself, why it is built the way it is, and perhaps with some documentation generated from servant.
• [x] Finally, one for the server, describing the design, why I used the various libraries I chose to implement it, and whatever else seems right to put in there.
