Add documentation

Used the following Spoons as a format reference:

- https://github.com/Hammerspoon/Spoons/blob/master/Source/Tunnelblick.spoon/init.lua
- https://github.com/Hammerspoon/Spoons/blob/master/Source/Token.spoon/init.lua

The Spoons documentation describes how to generate a required
`docs.json` file:

Thanks to Adam Matan (https://stackoverflow.com/users/51197/adam-matan)
on Stack Overflow for the tip on Make's `CURDIR` variable. Didn't know
that existed.
