extra debug comment
restore additional protection in minimization step
double crystal ball fix and reparameterization
allow splits resulting in non-convex leaf nodes
Add CBFast and GaussianFast
Add forced normalization RooAbsReal wrapper, total weight constraint, additional protection to force final convergence
additional protection for vdt-based pow function
further optimization to gaussian part of normalization integral
Add single and reverse single fast crystal ball pdfs
numerical and minimization improvements
move to double precision tree responses
double precision weights
improve positive gradient correction
more minimization tuning
further tuning and code hooks to allow single variable at a time optimization
extra protection in minimization for increase in likelihood
weaken protection on derivative value to avoid infinite loop or infinities
fix sign flip in numerical derivative protection
improvements (simplification) to minimization
redefine meaning of RooNormPdf to refer to the normalization constant itself, rather than the normalized value
