Template Lab

Write a lab that can serve as a reference for styles and guidelines that
are common in the project.  The lab folder itself can serve as a template for future labs.
I see you point.

We will just enforce the guideline that when imported, no code should be executed, and it must produce all needed plots (with our matplotlibrc) when run from the commandline.  Those are the likely the only two conditions that the plotting script should be required to meet.
