Looks OK. Just beware that list of R for which it works
is very short. Also, do you want to factor mutivariate
polynomials or univariate? Univariate polynomials
with Integer coefficients currently are handled in
GaloisGroupFactorizer. Dispatcher for univariate
factorization is in GenUFactorize.
UP in MultivariateFactorize is to allow recursively
building multivatiate factorizer from univariate one.
