Impulse Vibrations for iOS and Android (aka Taptic or Haptic Engine)

Impulse Vibrations is providing bridging between mobile haptic vibration API's and Unity3D Engine. Basically, it's an wrapper around UIFeedbackGenerator [iOS], Vibrator [Android], and View#performHapticFeedback() [Android].

Unlike most of the other Unity plugins, this will not provide you a common interface for each platform. Yet, it will give you more control over the code as a developer!

Important Note

- Taptic Engine and Vibrations will only work on the physical device. So consider the test this feature on the real device instead of Unity Editor.
