> This has the same goal as MAHOUT-1506, but rather than code the pairwise computations
in MapReduce, this will be done in the Mahout DSL.
> An orthogonal issue is the format of the raw input (vectors, text, images, SequenceFiles),
and how the user specifies the distance equation and any associated parameters.
