We added one new check to the partitioning stage for
MultiscalePartitioningEngine view which, after group validation, prunes
any species only connected by reactions with a log(flow/mean involved
species abundance) less than -30. Currently this is a magic number and
will need to be adjusted. These pruned groups succsessfully prevent
light elements getting vacumed up into QSE groups due to their overall
weak couplings to the entire network. This is important else the
conditioning of the QSE systems falls apart.
