 * rpiServo - This tiny C++ class is able to generate waveforms necessary to 
 * control servos. This class is derived from the rpiPWM1 class. 
 * It consists of a constructor that creates a 50Hz PWM waveform with
 * a 1.5ms ON time pulse...causing the servo to center itself to the
 * 90 degree position.
 *
 * The class also consists on a setAngle method that sets the angle of 
 * rotation to anything between 0 & 180 degrees
