// @Param: SETTLE_MS
// @DisplayName: Sonar settle time
// @Description: The time in milliseconds that the sonar reading takes to settle. This is only used when a STOP_PIN is specified. It determines how long we have to wait for the sonar to give a reading after we set the STOP_PIN high. For a sonar with a range of around 7m this would need to be around 50 milliseconds to allow for the sonar pulse to travel to the target and back again.
