---------------------------------------
Hey Jeff,
Minor request, it seems like you have some sort of reformatting going on that
causes the patch to contain all kinds of formatting changes that make it a lot
harder to see the actual changes.
In thinking about this a little bit more, is there a way to just name a vector
and a row in a Matrix. All I really want right now is to be able to track
which Vector is associated with which document, and I could do this by setting
a unique name on the Vector and having that serialized. The name itself could
be stored in the first entry (for SparseVector, it would have to coincide with
the sCardinality stuff.
I'm fine with all the other label stuff, too.
Also, the patch doesn't apply because of the JSONVectorAdapter
