Introduction of how to notify and react on events from within a ControlFlow

This sample shows how to notify an event to which a ControlFlow block is registered to. Another event is notified from ControlFlow which a function in this script is registered to.

1. Script notifying event -> ControlFlow reacts
2. Delay of 2000 ms within ControlFlow
3. ControlFlow notifying event -> Script reacts

This sample can be run on any device or on the emulator. After startup the delayed event triggers a function from the script which prints to the console
