Thank you for the contribution! However, your code currently does not pass our
coding standard, which is enforced by RuboCop. If RuboCop does not like the code,
it will fail CI tests, such as TravisCI and Appveyor.

To check your code locally, run:
```
$ bundle exec rubocop
```

To auto-correct, run:
```
$ bundle exec rubocop -a
```

Thank you!
