Implement style guide based test using rubocop

[coolbrg]

Rubocopis a great gem in Ruby for static code ananlyzer.
Adding it as part of tests would insure that code follow language code standards.

@navidshaikh Please add label test to this issue.

@budhrg Are you up for adding Rubocop. I would like to basically add it and be able to run its target (bundle exec rake rubocop). We can go for now with the default checks, but we don't need to fix all violations at once (maybe the most apparent ones). Instead we add a rubocop_todo to exclude the violations. The aim would be to reduce the items in the todo as we go, potentially also adjusting the rules, if we don't agree with them. FYI, rubocop_todo can be auto-generated.

Should not take long to do this and I think it would be a good start to converge on some common Ruby style.
