Add Dielman's Base Stylesheet Configurations

[joshwalsh]

Do we want to add any basic CSS structure to this based on Dielman's grid structure, and other basic settings & modules?

See my Yeoman generator project here https://github.com/bdielman/generator-baseline

All it requires is that you have Yeoman installed (which most of us do) and the generator. Then you answer a few questions in the command line and it sets up the directories/files, installs your npm and bower dependencies all without cloning the repo and manually changing and updating.

We could merge these for the D-I prototype.
