F-Snedecor Distribution

Description

Both distribution functions, "DistF" and "DistFinv", are correct in terms of
description but results are obtained changing the position of degrees of freedom .

Then ,
Real DistF (3.86, 9,3)= 0.949922 (TOL feedback)

and I think this is the result for Real DistF (3.86, 3,9)

In both next functions of tol/bmath/bprdist/prd.cpp

BDat BFSnedecorDist::Dist(BDat x)

and

BDat BFSnedecorDist::Inverse(BDat prob, BDat tolerance)

it was wrong the assignation of degrees of freedom

dfn = n_;
dfd = m_;
