This is not an urgent feature, but I would like to think a few items regarding how to design a law for this. Right now, we don't have a realistic sliding law implemented in ODINN. Furthermore, I think we also need to think a bit about having a cache per "physical component" or per coeffient. For me, it does not have much sense to have A and n independent of each other (they are not!!! You will never fit a regressor to just one of them, always the two of them or none), just as it is the same with p, q, and C for the sliding.

Great initiative! I think we should progressively implement all the classical sliding laws to have them for comparison and for scientific comparison.

A little bit like having different temperature index models and varieties in Muninn.jl.

You also need to update the formulae above between elseif model.Y_is_provided and these printstyled lines.
