Manage docker containers to run your project dockerized.

It expects a docker-compose file that specifies all services, and a service
named "main" that opens a shell for the project.

There are two subcommands:

- geordi docker setup
  Builds all docker containers.
- geordi docker shell
  Runs the docker service named 'main'.
