Generate release notes from PRs

By default this will look at the previous 100 commits from your local .git folder in your project. To Add release notes to an older project you might want to bump that WAY up.

Also you will need a valid GitHub token in your .env file.

GenerateReleaseNotes.new('your_org/your_project', 'path_to_location_of_prev_sha_file/previous-sha.yml', ENV['GITHUB_API_TOKEN'], true)

• Opt in (100% backwards compatible)

3 things that suck in React

1. Reusing logic (wrapper hell) think HOCs & render prop functions
2. Reduce “giant” components (too much boiler plate logic split across lifecycle methods)
