141025-2333 Our own API, is ready.

I made two AWT programs, one for importing models and textures, another
for previewing results on PC.

Guys, we can already start to focus on the real stuff now. Although I
can still make furthur encapsulation so that we can produce both Android
Cardboard and AWT programs.

And I shall change my focus to VoIP now.
