task-refactor

Taking legacy code from a project and task manager and refactoring.

I've been wanting to implement the refactoring techniques I've been learning, so I decided to JUST DO IT! I'll be following "Modernizing Legacy Applications" by Paul M Jones https://leanpub.com/mlaphp. I'll be adding my own notes as I go with tips or issues I run into.
