Overlapping between VGGFACE2 and FaceScrub

I made simple modification to your code, and found there are about 140 overlapping subjects between these two datasets.

I only checked a subset of FaceScrub used by MegaFace. It only includes 80 identities.

It is welcomed to share your checking results for the whole FaceScrub here.
