> 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.)
