Grant Ingersoll updated MAHOUT-137:
-----------------------------------
Attachment: MAHOUT-137.patch
Draft of KMeans conversion. Most tests pass except testKMeansReducer and
testKMeansMRJob.
In reading the testKMeansMRJob() it is not clear to me what that last part of
the test is doing (after the BufferedReader)
As for the Reducer test, I'm not sure why the Centers aren't matching up.
Some extra eyes would be appreciated.

> All M/R jobs should use Vector writable instead of encoding and decoding
> strings. We can have a separate utility that converts serialized GSON,
> Strings, whatever into the appropriate vectors. See MAHOUT-136 and
