+ IR array
+
+ Read the analog value of the IR sensors at the
+ bottom of the robot. The also-called line following
+ sensors are a series of pairs of IR sender/receiver
+ used to detect how dark it is underneath the robot.
+
+ The information coming from the sensor array is stored
+ into the Robot.IRarray[] and updated using the Robot.updateIR()
+ method.
