Remove ecut from PairDensity
After all this time, it turns out PairDensity does not in fact use ecut at all.
- Remove
ecut
parameter and corresponding attribute from PairDensity - In particular, this means
self.ecut
can't be None. (Looking at you, EXX) - Other classes are now responsible for normalizing the unit of ecut if they want to do that
- Since I got trouble with None vs default value (being 50. Sometimes), we now default to None which we normalize immediately to an actual value.
