OyenCov vs Coverband

Coverband is a great library being actively developed and maintained by Dan Mayer. It's like Simplecov, but to be run in production to track which lines of code are being executed, and which aren't.

Many teams have set up Coverband to learn about how their codebase is being used. However, it has not always been easy to make sense of the output report and know what to do with it.

OyenCov is like combining both Coverband and Simplecov together. We run in both Test and Production environments, and tell you:

1. How many Methods, controller actions, background jobs are in use and being tested, or not;
2. Which of those do we think you may need to increase test suite overlaps on
