Line follower
As mentioned in the first chapter, the line follower is composed of six pairs of emitter-receivers to sense six aligned points on the floor in order to determine how decentered the robot is with respect to the black line it will be following.
The line follower is also part of the GoPiGo3 API library. Its methods are detailed at https://di-sensors.readthedocs.io/en/master/api-basic.html#easylinefollower. The unit test we are going to perform consists of validating that the sensor can tell which side of a black line the robot is.
