Ted Dunning commented on MAHOUT-668:
------------------------------------
Style comment: Please add javadocs and remove @author tags
Real comment: Metrics like CityBlock already exist in Mahout. If you need to
re-implement them, you probably will have better
results if you use matrix/vector operations instead of explicit loops. This is
especially true when the assumptions that led
you to your loop structure are violated.
