Things remaining to be done before public release

Hi @ageorge and @dgeissbuhler,

FYI, here is the list of things that needs to be done for the paper package before releasing it. I tried to make it in the right sequential order:

• implement proper dark frame subtraction in bob.io.stream
• release publicly bob.ip.stereo
• release publicly bob.io.stream
• release publicly bob.db.hqwmca and bob.db.brsu
• merge add-hqwmca branch of bob.pad.face (bob.pad.face!101 (closed))
• distribute HQ-WMCA through dataset portal (ideally at http://www.idiap.ch/dataset/hqwmca)

I assigned @dgeissbuhler to it, since most of the stuff involves 'his' packages, but I will still be following that and certainly act on some of the points in the next few weeks/months !
