Layer 2->3->4 schema relationships

[eddie-knight]

After all the recent changes were applied, Layer 4 feels like it needs a big cleanup of how we're managing cross-document references.

I think we're gonna need to remove some mappings to reduce redundancy and focus on the important pivots. And we need to add mapping references. And probably include some connection to the policy in the evaluation plan.

• TODO: Handle mappings in the same fashion as the other layers
• EvaluationLog should have a better connection to the evaluation plan beyond just referencing the procedure

Current flow of information... something feels off.

We say that Layer 4 should take marching orders from Layer 3, but currently we don't reflect that relationship in either the Assessment Plan or Evaluation Log. Ideally, the Assessment Plan will be generated with information specified in the Policy.

Also, the Evaluations should be executed based on the plans, but currently the only relationship is at the lowest level in Logs. It's possible in the current state for a Gemara test framework to read the plan to determine which tests to run, but I would expect evidence of that to be presented somewhere higher than the log of the individual assessments.

Perhaps this is what we're going for... Although we're still missing some mappings within the Evaluation Log.
