feature: adding an edge for file to symbol

[johnynek]

Sculpt could be exactly what I need to break large scala targets into minimal dags for bazel to build.

The only thing missing is a mapping of which file each symbol is defined in, since bazel’s finest units (currently) are files.

How hard would it be to add this mapping? Something like [{ “file”: “Foo.scala”} , “produces”, {“sym”: [...

If you can coach me through this, I’m happy to send a PR if you thing this would be easy ish for someone unfamiliar with the compiler/plug-in.

yes, I think this is a modest, doable change, and if you get stuck, I'd be happy to help get you unstuck.

Thanks for the reminder. I’ll take a stab at this.
