Maybe we want to use the Lean pretty-printer to format our code? (leanprover/lean4#369)

Yes, it would be great to have the code auto-formatted. My understanding is that the existing pretty printer is not quite ready for production yet.

This PR adds an initial formalization of Cedar in Lean (RFC-32), co-authored with @bhaktishh.
The initial formalization contains a full specification of the Cedar evaluator, along with the proofs of the basic authorization and slicing theorems. It also contains a specification of strict validation (RFC-19).
To complete the formalization, future PRs will (1) integrate
cedar-leaninto the DRT framework, and (2) prove that strict validation is sound.By submitting this pull request, I confirm that you can use, modify, copy, and redistribute this contribution, under the terms of your choice.
