In this tutorial we will walk you through the creation from scratch of a human readable encoding system, and to make it more interesting, give the option of varying the details of the scheme produced, how to turn a library into a microservice, including simple concurrency

This tutorial demonstrates the use of almost every possible and important feature of Go. A "toy" implementation of a gRPC/protobuf microservice is added in order to illustrate almost everything else.

In order to demonstrate synchronisation primitives, waitgroups, atomics and mutexes, the service will keep track of the number of invocations, print this count in log updates, and track the count using a concurrent safe atomic variable and show the variant using a mutex instead, and run an arbitrary number of concurrent worker threads that will start up and stop using waitgroups.
