A disciplined method to fix Rubocop TODOs

Here, a listicle of advice you never asked for!

A method to locate and fix linting errors in Rubocop one at a time:

• choose a “cop” from the .rubocop_todo.yml file
• remove the line which includes the .rubocop_todo.yml
• rubocop --only Lint/IneffectiveAccessModifier
• fix issues and test fixes with the --only invocation
• rubocop --auto-gen-config to regenerate the .rubocop_todo.yml file
• git checkout .rubocop.yml to add back include line
• commit this change with the name of the “cop” used

I really really tried to use it at FakeFS.
