A simple Elixir experiment with the OTP state machine gen_statem
defmodule Turnstyle do
@moduledoc """
This state machine emulates a turnstyle gate that has a rotating bar
and a coin slot. If the gate is locked a coin must be inserted to unlock
it, and then the bar will rotate to let you through when it is pushed.
The bar will then lock back in position.
