> This is similar to the same reasoning behind the fix for MAHOUT-957. The
> desired output is term frequency vectors, but I want terms filtered by their
> min and max DF values. This might be valid in LDA, where tf vectors is
> desired for input, but filtering out the maxDFPercent is also useful.
> Currently minDF and maxDFPercent are only used when calculating tfidf, and
> the original tv vectors are not updated to represent the term filtering.
