Known Limitation: PF Unit test subgrid hierarchy isn't filled out

[ekluzek]

For the PF unit tests of the Fortran code the subgrid structure is typically only filled out for the subgrid level of interest. For example for patch arrays only for patches. So it won't necessarily have proper mapping for gridcells. Landunits, and columns. Some unit tests populate more than one layer, but most do not populate all layers.

This can matter if you expect all layers to be populated. For example if you use the point option to endrun to write information on all layers.

We could restructure some of the unit test subgrid handling infrastructure to make sure courser levels were handled. I think we could design it such that changes would be there and not anywhere else. It would require some assumptions, but seems like it could be done.

However, right now it doesn't seem like there is enough of a reason to do it. So we'll probably leave this alone.

I brought this up with @billsacks a monthish ago and we chatted about it and came to that conclusion. It could be done, but probably not worth it.
