Direction for Packagescape?

This isn't an issue more of reaching out. I used to do some work with thin films, simulations, etc. What is the over-all direction for this package and it's related ones (TMMOptics, etc)?

Do you plan to support other rigorous methods? It looks like you are working with Fresnel based solutions, but surely others exist (FEM, RCWA, etc).

I may see some room for collaboration if I can get approval from some colleagues to share code I have written during graduate school. If not - I will maybe start from scratch and see how it goes. The code wasn't written in Julia anyways...

No file, test, or entry point is named; this is a request for project direction rather than an implementation task. Start by reviewing the repository description and existing scope, then seek maintainer guidance on whether additional rigorous methods such as FEM or RCWA are intended before defining any work.
