GenStage Tutorial

Introduction

So what is GenStage? From the official documentation, it is a "specification and computational flow for Elixir", but what does that mean to us?
There is a lot to something that can be described as that vague, and here we'll take a dive in and build something on top of it to understand its goals. We could go into the technical and theoretical implications of this, but instead lets try a pragmatic approach to really just get it to work.

First, Let's imagine we have a server that constantly emits numbers. It starts at the state of the number we give it, then counts up in one from there onward. This is what we would call our producer.
