Add automated tests.

Virtually every need for an automated test is being refactored into split projects.

I have sooo much unpublished code just waiting to die in a single hard drive failure, it's not even funny. Been working on splitting it out for over a year now.

The two main packages:

• https://github.com/phpexpertsinc/JWTHelper [~50% modded on my local box]
• And the wholly unpublished JWTGuardian.
