Load positivity datasets with cuts
Created by: scarlehoff
We always skip the cuts when loading positivity datasets. I'm not entirely sure why (it has always been done like that, maybe some parts of the code needs the positivity not to be cut)
However, now the positivity sets and fktables should be in the same footing as the others, so in principle we could also cut (in x
for instance). Maybe removing this method (so that it goes to the parent, which applies the cut) is enough, but it should be tested.
