Description
Currently, soil N is added to all age classes, including those that do not yet exist. Addition of nitrogen should only be initialized for PFTs for which veget_max > min_stomate.

This issues should be tested with a run.def using age classes for the forest PFTs. In a run of 140+ years, it was observed that there was LAI in two age classes of the same MTC, this should not happen. The model crashed on an ipslerr in stomate_litter --> soil_n_min present in pixels without veget_max. There are two places to start looking: (1) the code where soil_n_min is initialized and (2) the code where soil_n_min is moved from one age class to another (age_class_distribution).
