I am not completely sure it was doing what we expect in the first place,
and I think the interface is
bad and does not generalize to unstructured. I want to fix it (fairly
badly), but I got sidetracked on
things that people are demanding. Its fine with me if we revert that branch
from next, but I did not
think anyone was looking at this.

  Thanks,

     Matt
