The database that was chosen here is SQLite, because it's dead simple to
setup and more than enough for this project.
Please note that I took some liberty with the assignment. I chose to use
a numeric field for the `id` column of an item. This leverages automatic
creation and incrementation of the id by SQLite itself.
This initial version is purposely extremily limited:
* `GET /ahoy` endpoint, just to check the server is alive
* `GET /items` endpoint, always returns the same item
* `POST items` endpoint, checks and print request payload, no
persistance
* calling any other route defaults to a 404
