Change in meaning of fractions
--------------------------------
The transition from dv.py to qdv.py changes the meaning of the
warning fractions : it used to be fraction of compared elements with deviation exceeding cut
it is now fraction of photons with aggregated max deviation exceeding cut
This tends to reduce the fractions, but its more meaningful as single elements dont go wrong
on there own : usually its the photon that goes wrong with many elements deviating together.
So a fraction of deviant photons is more pertinent.
