Integration of rubocop?

[jszwedko]

Hey!

I was wondering what the opinion of integrating Rubocop for style-checking would be. In addition to enforcing a consistent style, it also helps find issues like unused variables, improper equality operators, missing documentation, and other possible bugs.

Figured I'd ask before integrating it since it'll take a little time to address the issues that rubocop cannot autocorrect.

I have no complaints about adding rubicop

@jszwedko I am a rubocop fan, and if you create a feature branch, I can take a look at fixing some of those items as well. Whenever a submission comes in that doesn't validate against, that can be part of the evaluation process at that time.
