Refactor - check out these ideas

I played around with some ideas for a new interface to this project. No need to merge this PR. I just wanted you to take a look at the changes I made to the README to see if you like that as a potential UI.

Obviously you have a better idea of exactly how you're wanting to use this tool, so weigh in on what I wrote up. Once we settle on and end-goal, we can start working on refactoring this baby into a command line tool! :+1:
