 workflow. It is organized in this way so that it can be packaged as a Python
 package and later installed in the VM workers executing the job. The root
 directory for the example contains just a "driver" script to launch the job

 The advantages for organizing the code is that large projects will naturally
 evolve beyond just one module and you will have to make sure the additional
 modules are present in the worker.
