In inbo/forrescalc: Calculation of Aggregated Values on Dendrometry, Regeneration and Vegetation of Forests, Starting from Individual Tree Measures from Fieldmap

# This script generates an overview of all variables containing class data,
# containing their name, the name of the variables that represent min and max,
# and the transformation that should be used to deal with these data.
# In case of coverage, transformation is based on the class widths of the most
# abundant coverage classes
# (This table is used in create_statistics().)
