Description

An astute MiA reader points out that the FileDiffStorage class does not have a way to read diff counts, or the number of item-item pairs that resulted in the average diff. It is assumed to be 1, which causes it to be pruned quickly. The SlopeOneAverageDiffsJob needs to likewise output counts.
