AccelerometerService (Attach 4.0.11 API)

All Known Implementing Classes:

AndroidAccelerometerService, DummyAccelerometerService, IOSAccelerometerService, MobileAccelerometerService
```
public interface AccelerometerService
```
An accelerometer measures the acceleration force that is applied to a device in all three physical axes (x, y and z).
The AccelerometerService provides a read-only acceleration property that is updated at regular intervals by the underlying platform implementation. A user of the AccelerometerService can listen to changes of the acceleration force, by registering a ChangeListener to the acceleration property.

Example
```
 AccelerometerService.create().ifPresent(service -> {
      service.start();
      Acceleration acceleration = service.getCurrentAcceleration();
      System.out.printf("Current acceleration: %.2f, %.2f, %.2f",
              acceleration.getX(), acceleration.getY(), acceleration.getZ());
  });
```
