Line Follow in Teleop

[jhellr13]

I recently saw the video from team 1678 that shows them pressing a button, and the robot drives forward, finds the line, and drives to the T. I have been thinking about it, and am wondering how they did it. I think that you just need to take the line following code from the autonomous vi, and put it in a case structure in the teleop vi. Does this sound correct? I'm wondering if they changed anything in order to make it drive straight to the line, rather than spin in circles.
I'm not looking to steal their code and awesome work. I just think this could be of some help to our team, and would like to know how they did it.
