With pocl builds fixed, we can now also use the OpenCL implementations in gearshifft :)
We moved to a new GitHub org! Now make the code and docs reflect that.
Adds the `gearshifft` package, a benchmark suite for heterogeneous implementations of FFTs. Adds clFFT, a software library containing FFT functions written in OpenCL. see: https://github.com/clMathLibraries/clFFT
