Changeset 14320 for trunk/psLib/src/math/psMinimizeLMM.h

Message:

dLinear, the linearized change in the chisq, was being calculated
AFTER the parameters were set to their limits. this is inconsistent
with the assumptions, and resulted in impossible negative values for
dLinear, which in turn caused problems for the fitting convergence.

I moved the call to dLinear into GuessABP, and modified the APIs a bit
to deal with this.
