Porting nomad and autodiff to ArrayFire #17

Does anyone know how hard it is to port to ArrayFire? ArrayFire has OpenCL, CUDA and CPU backends and many nice language bindings as well.

This will be highly nontrivial given the global autodiff stack. Individual functions could utilize such APIs but it would have to be in a bespoke manner and Nomad is aimed for hardware-independent support. If anyone is interested fork and give it a try, but for now there won't be any movement in Nomad itself.

@betanalpha Thanks a lot for your answer. Maybe, when I have some time to work with Stan, I'll give it a try.
