Detailed Description

Calculates the size effect with a compound exponential function.

This uses two different sets of parameters, depending on whether a tree is infected or not.

Size Effect is calculated as:

SE = (1-a*exp(b*(diam/100)))*exp(c*((diam/100)^d))

where diam is the diameter of the target tree, in cm (d10 for seedlings, DBH for everyone else); and a, b, c, and d are parameters.

Insect infestation is determined by the behavior of class clInsectInfestation or clDensDepInfestation. This class expects to find a "YearsInfested" int data member to be present for all trees to which this behavior is applied.
