field names are misleading.
plant_parm_read.f90:60-63 reads plants.plt columns into these slots and the carbon model uses
%lig_frac as bg_lig_frac and %str_frac as ab_lig_frac. Math is correct, names mislead.
Renaming touches multiple files; flagged for the model devs to resolve.
Nodes of different colours represent the following:
Solid arrows point from a derived type to the parent type which it
extends. Dashed arrows point from a derived type to the other
types it contains as a components, with a label listing the name(s) of
said component(s).
Where possible, edges connecting nodes are
given different colours to make them easier to distinguish in
large graphs.
