Lance Norskog commented on MAHOUT-643:
--------------------------------------
Is this Chebyshev or Manhattan distance? Or is it a third formula?
If the first, could they all be named consistently?
If the second, could there also be a DistanceMeasure?
This is the kind of thing that breaks the sanity of new users.
