org.apache.mahout.cf.taste.impl.common.CompactRunningAverage

Like {@link org.apache.mahout.cf.taste.impl.common.FullRunningAverage} but uses smaller values (short,float) to conserve memory. This is used in {@link org.apache.mahout.cf.taste.impl.recommender.slopeone.SlopeOneRecommender} since it may allocate tensof millions of such objects.
