Lance Norskog updated MAHOUT-812:
---------------------------------
Description:
ConfusionMatrix does not support Writable. This patch adds that feature.
ConfusionMatrix is a subclass of MatrixWritable.
Since ConfusionMatrix is somewhat less than useful without the row/column
labels, and MatrixWritable does not support writing bindings (it only saves
numbers), this patch fixes both.
Includes unit test for ConfusionMatrix (previously missing) which includes
exercise of MatrixWritable support for numbers and labels. (There is no
independent unit test for MatrixWritable.)
