v0.1.0

This is a pre-release of gearshifft. We are still in the initial development phase, so other platforms than Linux are not supported yet and changes of the gearshifft API are likely. gearshifft v0.1.0 provides FFT client wrapper for cuFFT, clFFT and FFTW to benchmark plan creation, data transfer, FFT and inverse FFT as well as buffer allocations and context/device initialization. The goal of this release is to satisfy the upstream requirements of gearshifft_publication;
