  // Servo API

  // min()
  //
  // set the servo to the minimum degrees
  // defaults to 0
  //
  // eg. servo.min();

  // max()
  //
  // set the servo to the maximum degrees
  // defaults to 180
  //
  // eg. servo.max();

  // center()
  //
  // centers the servo to 90°
  //
  servo.center();

  // move( deg )
  //
  // Moves the servo to position by degrees
  //
  // servo.to( 90 );

  // sweep( obj )
  //
  // Perform a min-max cycling servo sweep (defaults to 0-180)
  // optionally accepts an object of sweep settings:
  // {
  //    lapse: time in milliseconds to wait between moves
  //           defaults to 500ms
  //    degrees: distance in degrees to move
  //           defaults to 10°
  // }
  //
  // servo.sweep();
