face recognition implementation is racist

[paulbrodersen]

I am testing the no-openmdao branch and whenever my non-Caucasian friends want to try it out, the face recognition fails to detect them. It works great for me though (I am a whitey).

Hm, that's odd. I've also tested it with my non-white friends and it didn't seem to have any trouble. I'm using the built in haar face detection cascade in OpenCV. It might be worth trying one of the other haar cascade files included in the repository to see if there is another one that seems more generally applicable.
