a-c-r feature to automatically generate scatter worfklows
Typically a workflow is written to operate on a single sample, and is executed many times over a batch of samples.
CWL has a useful pattern with "wrapper" workflows, which is a workflow of a single step that calls out to the real workflow. This wrapper workflow can perform a scatter.
Writing these wrapper workflows is straightforward and mechanical. It would be convenient to have an a-c-r option that generates a scatter workflow for you. This could be extended to also run the scatter workflow automatically.
