Added unit tests in response to issue #14

[NewMountain]

Hi @flacle !

As mentioned in issue 14, I would like to help out with the issues in the backlog, but wanted to make sure there were tests in place so that I could be sure I wasn't breaking any existing functionality.

Please let me know what you think and, if you are comfortable with the idea, I would like to help you close out some of the other issues.

Thanks again!

Changes:

• Minor tweaks to Formatting
• Added a section about contribution
• Added section about how to test
• Added a few words about present and future organization
• Left all existing code in place
• Created two new functions to make more modular and easier to test
• Moved a few lines of existing code into those two new functions
• Added unit tests to cover core functionality

Hi @NewMountain , thanks for your contribution! I've finally have organized a bit here to get some time again to focus on this repo. I will merge your two pull requests, and we can discuss/chat how your participation. I don't think it makes sense to rely on one person (me) as the gatekeeper for this handy tool.

Let me know. Francis
