PMProbabilityDensity>>#privateInverseDistributionValue: has a weird dependency to PMCDFNewtonZeroFinder

[jecisc]

PMProbabilityDensity>>#privateInverseDistributionValue: is using PMCDFNewtonZeroFinder and this cause a problem of dependency. But while discussing with Oleks we think that maybe this should not use newton method at all.

I don't have the right background in math to deal with this issue so if someone has knowledge on this topic I would really appreciate some help.
