First try to resyntax

I just novice for this gem, and want to resyntax it first. What I mean is there are a lot of ruby-style-guides, I prefer most popular: [https://github.com/bbatsov/ruby-style-guide](ruby-style-guide) and there is gem for appropriate ruby style: [https://github.com/bbatsov/rubocop](rubocop).

So, I ran this gem and saw huge amount of offences and repair little part of ruby 'bad' style.

Just try go to the root of the_comments, then `gem install rubocop` and then run `rubocop`
