Description

It would be a good utility to be able to map output datasets of certain coordinators to input datasets of certain others. This would help pipeline users to see the relationships among the data that each stage waits on, and can be extended later on the lines of data-driven triggering. This is achievable only for a constant sample space of coordinators to begin with.
