This behavior evaluates mortality according to the density of conspecific trees in the neigborhood. The function is:
pm = g * exp(-exp(h - i * Den))
where pm is probability of mortality, and Den is neighborhood tree density in stems/m2. The target tree is deliberately counted.
This class's namestring is "densitygompertzmortshell".
This class's parameter file call string is "Gompertz Density Self Thinning".
