Parallel Workflows

This example uses two parallel child workflows to demonstrate paralleism.

Print: parent workflow start
Starting child workflow '900eef73-57c1-4891-a95b-b619f0e7f86d'
Activity message: Hello from co2 (1), received: Child workflow '900eef73-57c1-4891-a95b-b619f0e7f86d' says hello, got input: parent workflow start
