-------------------------------------------------------------
M/R version of previous patch.
The only thing it does is to compile. I'll be replacing the todos with code
soon enough. It is still Maven only!
One thing I'm not quite certain about how to solve is how to handle features
that are class values, for instance the news group when parsing 20NewsGroups.
Comments most appreciated.

> A set of classes that builds matrices from text.
> Currently the API consists of TokenMatrixBuilder and TokenInstanceBuilder.
> Should be thread safe.
> PostReader imports 20news-bydate. This takes several GB heap. It would be
> nice to bounce the data via JDBM or perhaps using the PersistentHashMap in
> MAHOUT-19.
