Experiment with and write up a design document for the line-following sensor.

Describe how it works. (Sensors return what kind of values, and what do they indicate?)

Describe how we could use it in our existing robot architecture. In autonomous mode, could we hand off control to the drivetrain to this component, or would we just it in the main loop to just ask for corrections and then apply them to the drivetrain?

Propose a software interface for this line following sensor.
