Line Following Tutorial

Here's a short and informative tutorial to creating a line following robot. This is a lot simpler than most PID control Line Followers, and still a lot smoother than simple Switch (left-right) Line Followers.
Thanks for sharing Stefan!

But I think it's still a helpful tutorial for people (especially FLL participants) who would like to improve their left-right switch line following programs.
