Printing workflows

To view its contents, a workflow can be printed at any time:

with scriptcwl.WorkflowGenerator() as wf:
  print(wf)

For an empty workflow, this looks like:

#!/usr/bin/env cwl-runner
cwlVersion: v1.0
class: Workflow
inputs: {}
outputs: {}
steps: {}

In a printed workflow, steps are referred to by their absolute paths. Therefore, do not use this method for saving workflows. The absolute paths make them unportable.
