project 11 connections

Repository originally created privately at Arkency by Paweł for the Rails Architect Master Class. Contains multiple implementations of the same JIRA-like issue aggregate (state machine), sharing a common test suite so each implementation just needs to make the tests pass. New implementations are added by copying a directory and a Makefile section. Made public on GitHub one hour before this talk, with a mutation-testing script included. Krzywda invites audience contributions of new implementations.
