[PIGMI] BlueGin - Android C++ game engine

[Doug]

Physics, particularly, also gets a big speed up from a c implementation.

It's a pity you have to require android 2.3+ to be able to the
NativeActivity; using that you could write your entire engine in c, and
basically have one code base for iphone and android. :3 that would be pretty
sweet.
