Add affiliation for Warner & NIH acknowledgement.

Despite this not including research examples from me (I was trying; difficult to get clearance on short notice) the particular grant directly supporting me at the moment is an F30. This provides rather broad support. So, even though I have worked on this in my free time, the [standard NIH acknowledgement](https://grants.nih.gov/grants/acknow.htm) needs to be present.

If anyone else (@jni ?) needs to toss a grant number in there, I left it nonspecific.
