Create a Configuration interface

[cycomachead]

i"m trying to clean up the way configuration is handled.

This is a start, but I'd like to think about how we can get to "Modules" We have 'slip days', 'late adds', 'check offs'. All have distinct configurations, but shared data as well.

Config file location is TODO. Methinks it should actually be a top-level deal, so it's easily tweaked.

So is the idea that we then run this file through something like this: https://nodeca.github.io/js-yaml/

And then use that object in our code?

Yeah, basically.
