Original description

It would be cool if the Servo library could use either of two strategies: hardware PWM control if the servos are on pins 9 or 10, and software if not. This would basically be combining the old servo library with the new one. See also PWMServo (http://arduiniana.org/libraries/pwmservo/) for an alternative version of the old (hardware-control) servo library.
