Hound-like Rubocop utilities

The scold command calls Rubucop using the same configuration as Hound merged with .rubocop.yml file in the current directory, if present, then merged with ~/.rubocop_strict.yml if present.

The hound command calls scold with changed git files, if any; otherwise does nothing. Unlike the Hound web service, this command inspects entire files, not just changed lines.

Add to Gemfile:

gem "scold", require: false

From command line:

bundle exec scold [rubocop-options] [files...]

bundle exec hound [rubocop-options] 

bundle exec rspec # test locally
rm *.gem; gem build *.gemspec # build locally
gem push *.gem # publish to rubygems.org
