Servo moves to a touch input, via Andrew Quitmeyer

ServoMoverToMeasureTouch

/*
   This is an extension of Martin2250's ADC touch examples
   to have the library built in, for rapid deployment in workshop settings

   In this one, you can hook a servo directly up and the servo will move with regard to the cap touch measurement
