I made some minor tweaks to the font size and color of the body text.
Plus, there were some changes to the head.html as I tested out different
font families. In the end, I stuck with Merriweather Serif and Lato
Sans-Serif.

Also, a new post was created. The topic was my Mac setup for research.
This included two images for the post.
