        This method currently validates the workflow object with the use of
        cwltool. It writes the workflow to a tmp CWL file, reads it, validates
        it and removes the tmp file again. By default, the workflow is written
        to file using absolute paths to the steps. Optionally, the steps can be
        saved inline.
