Here's the simplest example showing how to do functional options in Golang.
They're a great way to enable users to set options and ease adding new options later.

The initial goal of this project is to use the raspberry pi in place of my Wireless Range Extender and then going from 3 wireless networks (2.4ghz, 2.4ghz extended, 5ghz) at home to only one (5ghz). This way I'm reducing the exposition to radio waves for the whole familly at home.
