 * This application is a console application that allows for easy use of the
 * PID (proportional, integral, derivative) algorithm.  You start the application
 * with 6 arguments, documented below, that set up the algorithm.  Then, when
 * you send data to the application through stdin, it runs it through the PID
 * algorithm and sends the output through stdout. kP, kI, and kD are usually
 * REALLY SMALL VALUES (0.X, 0.0000XX and 0.0000XX, respectively).
