88660 adding note field to bulk upload

I don't know the name of the header for the csv. For now I just used "Note", but we should figure out what standard will be used. I'm using keyword arguments so it should be easy to add any more attributes to the bulk import in the future.
We're still running a fork of nucore that runs on 1.9.3, so we can't use the keyword splat.  Can we just pass around an optional hash instead?
