There are quite a few things that are backward incompatible in this first iteration of the code (e.g. demanding experiment number or axis titles). I can improve that before landing.

Do you have an example of using this generalisation of the K-matrix that could go into the examples dir?

Not yet, but very happy to add one when this implementation has been tested a bit more in my fits. Can I do this later, or shall I pause D41 landing until I've gained a bit more experience with the K-matrix in D0 K+?
