Thanks! I don't like the AT implementation myself either, although I'm
also kind of happy that I made AT do what I want. ;)

Ack. However, some user-friendlyness is still missing. See my other

I think it's dead by now. It didn't seem active a few years ago when we

model that allows a lot of things in general but is missing the
specificity of Alphaflow's library.
