Tango 360 Video Player

Load up 360 Youtube videos and the view them in virtual reality.

The app is pretty self explanatory so I'm going use this section to talk about the problems I've been having in the hopes someone can point me in the right directions

1. I can't seems to get the youtube data api loaded under an android key, so i used an ios one instead. The sha1 seems to not be verifying one my end.

2. I tried really hard to get this working with the experimental augmented reality package and I could not get the material to cull the front faces. I suspect this is because occlusion in the ar demo.

Those are the main ones with the tango, I have two general problems I need to address with the 360 youtube data api, is a way to detect if youtube videos are 360 or not and to tell if they fail to load.
