47! Changes in the course of the canopy-model modularization:
48!   module plant_canopy_model_mod added,
49!   definition of array cdc (canopy drag coefficient) removed, since it is now
50!   defined purely as a single constant value (see module plant_canopy_model)

56! kind-parameters added to all INTEGER and REAL declaration statements,
57! kinds are defined in new module kinds,
58! old module precision_kind is removed,
59! revision history before 2012 removed,
60! comment fields (!:) to be used for variable explanations added to
61! all variable declaration statements

72!> the array of the canopy drag coefficient, if the user has not chosen any
