Rubocop config

[edwardloveall]

Looks like @gfontenot was working on some of these changes already. I figured I take it one step further and introduce the rubocop config file so anyone can lint their code before pushing up for a PR. This might help if people run into a lot of hound warnings.

Possible next steps:

• Add instructions for linting in the contributing document
• Lint all the files in the repo and fix errors (646 errors at the moment)

To be clear, is this the current default rubocop config from Hound?

[edwardloveall]

Yes
