Event-based Greeting Example

This example demonstrates a workflow that waits for a greetingcloudevent event. When the event is received, a state will be triggered using the data provided by the event.

The generate-greeting workflow generates the greetingcloudevent that the eventbased-greeting workflow is waiting for.
