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.
From a stylistic standpoint, I find it better to pass the names of the files I want to write to as arguments to the functions.

Good idea showing how to put labels, legends, and titles there too. We should add that matplotlib's LaTeX support *should* be used for any sort of math needed in the plot labels.
