Spatial subset using a shapefile or something similar?

[Balinus]

Hello!

I was wondering if there was an easy (i.e. an example somewhere in the tutorials) way to subset a cube using a shapefile or something similar (e.h. irregular polygon)? I have looked but haven't found something that can be easily reused. For a bounding box, it is easy of course with the nice syntax that YAXArrays and DimensionalData.

Thanks for any help!
