 GPU Array package for Julia's various GPU backends.
 The compilation for the GPU is done with [CUDAnative.jl](https://github.com/JuliaGPU/CUDAnative.jl/)
 and for OpenCL [Transpiler.jl](https://github.com/SimonDanisch/Transpiler.jl) is used.
 In the future it's planned to replace the transpiler by a similar approach
 CUDAnative.jl is using (via LLVM + SPIR-V).

 # Why another GPU array package in yet another language?
 
 Julia offers countless advantages for a GPU array package.
