Description

When running a scatter over a batch of samples, some samples may fail, but we want to continue the workflow with the samples that succeeded. Implement a CWL extension which alters workflow behavior so that failed steps steps produce null values but allows the overall workflow to keep running.

This may require adding new behavior to cwltool and if generally useful, could be a standards-track feature for a future version of CWL.
