vibrate property

Specifies a vibration pattern for devices with vibration hardware to emit. A vibration pattern can be an array with as few as one member. The values are times in milliseconds where the even indices (0, 2, 4, etc.) indicate how long to vibrate and the odd indices indicate how long to pause. For example 300, 100, 400 would vibrate 300ms, pause 100ms, then vibrate 400ms.
