Improve TransposeJob to use a Combiner

Project: Mahout
Issue Type: Improvement
Components: Math
Affects Versions: 0.6
Reporter: Sebastian Schelter
Assignee: Sebastian Schelter
Attachments: MAHOUT-777.patch
I saw that TransposeJob has a comment that it needs a rewrite to use a
combiner. If we emit vectors instead of MatrixEntryWritables we should be able
to "merge" them in a combiner.
