Describe the feature request

As a planner and plan reviewer, I would like to be looking at a Plan and know what files (especially what file versions) are being used to create the generated elements in the Plan and be able to trace Activities and Resource impacts back to the source files.

It would be nice to have a way to view in the AERIE UI a kind of "this Plan brought to you by files x, y, and z" final credits-like info and follow Parent->Child spawn and Scheduler Goal links back to a source file (if there is one) or other source.

Traceability will be particularly helpful when source files are no longer valid or have changed and all the scheduled descendants need to be wiped out or shifted within a Plan.

Start by reading the related discussion in issue #1318 and the traceability requirements described here. The request is complete when the UI can identify the files and file versions behind a Plan and link Activities, Resource impacts, Parent->Child spawns, and Scheduler Goal relationships back to their sources.
