EECast: Intro to Feature Lines

Eric and I are visiting New Hampshire this week and had the chance to discuss topics for the next few months of EECasts. We’re definitely reading the comments, and will be working to pull in a Part Builder session, a pipes session, and a lots session, but next week, I’m going to run through feature lines.
