Set up contribution infrastructure for biojs repos

[DennisSchwartz]

Background

We should set up a formal process for contributing to biojs code repos.
That means the workman, the websites etc.

All input on this discussion is welcome. If there aren't any objections I will implement the process we use at Repositive and that seems to work very well for us.

Overview

• The master branch is protected. Contribution can only happen through pull requests.
• Pull requests need to be reviewed by a contributor
• Pull requests are classed into three categories
  • [F] Code changes for enhancements or new features
  • [B] Bug fixes
  • [S] Support changes. README, settings, deployment files etc.
• PRs are only merged using squashed commits. This provides a cleaner changelog.
• Every PR needs to pass automated tests and linting.
• Test coverage cannot decrease with PRs.
• Test coverage needs to be at least 85% and are at the discretion of the reviewer.

Todo

• Create CONTRIBUTE.md file with contribution guidelines
• Setup Circle CI integration for tests
• Setup test coverage testing
• Setup linter and automated linting

Done

So far I have:

• Enabled CircleCI for the biojs organisation
• Set up testing environment and linter for the new workman repo
