feat($prettier-eslint): Integrate prettier-eslint

As discussed in:
- #57
- kentcdodds/prettier-eslint-atom#28
- prettier/prettier#758

This commit completely refactors the repo. We now allow using
prettier-eslint as an option so that you do not need to install
a separate plugin (prettier-eslint-atom).

Under the hood, almost all of the code has been refactored and
covered by Jest integration tests. We also implement Babel and
many of the devops/build configurations that Kent Dodds authored
in the prettier-eslint-atom repo.

Resolves #57

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at kent+coc@doddsfamily.us. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+# Contributing
+
+Thanks for being willing to contribute!
+
+**Working on your first Pull Request?** You can learn how from this *free* series
+[How to Contribute to an Open Source Project on GitHub][egghead]
+
+## Project setup
+
+1. Fork and clone the repo
+2. `$ yarn install` to install dependencies
+3. `$ yarn start validate` to validate you've got it working
+4. Create a branch for your PR
+
+This project uses [`nps`][nps] and you can run `yarn start` to see what scripts are available.
+
+## Add yourself as a contributor
+
+This project follows the [all contributors][all-contributors] specification. To add yourself to the table of
+contributors on the README.md, please use the automated script as part of your PR:
+
+```console
+yarn start addContributor <YOUR_GITHUB_USERNAME>
+```
+
+Follow the prompt. If you've already added yourself to the list and are making a new type of contribution, you can run
+it again and select the added contribution type.
+
+## Committing and Pushing changes
+
+This project uses [`semantic-release`][semantic-release] to do automatic releases and generate a changelog based on the
+commit history. So we follow [a convention][convention] for commit messages. Please follow this convention for your
+commit messages.
+
+You can use `commitizen` to help you to follow [the convention][convention]
+
+Once you are ready to commit the changes, please use the below commands
+
+1. `git add <files to be comitted>`
+2. `$ yarn start commit`
+
+... and follow the instruction of the interactive prompt.
+
+### opt into git hooks
+
+There are git hooks set up with this project that are automatically installed when you install dependencies. They're
+really handy, but are turned off by default (so as to not hinder new contributors). You can opt into these by creating
+a file called `.opt-in` at the root of the project and putting this inside:
+
+```
+commit-msg
+pre-commit
+```
+
+## Help needed
+
+Please checkout the [ROADMAP.md][ROADMAP] and raise an issue to discuss
+any of the items in the want to do or might do list.
+
+Also, please watch the repo and respond to questions/bug reports/feature requests! Thanks!
