Create API documentation pages

[oanylund]

Create documentation pages for API.

Create pages documenting routes. How its implemented is not important.
Pages will be mounted to /api root response.

My suggestion is to use swagger.io. See live demo.

If someone is interested in taking on the task, feel free to ask questions.

I will fix this issue @oanylund . Swagger is the way to go.
