Overall summary

New functionality

New prior CudaRelativeDifferencePrior (use Cuda Relative Difference Prior in .par files), only available if the CUDA toolkit is found during building. Results are identical to RelativeDifferencePrior up to numerical rounding issues. However, the code is currently limited to 3x3x3 weights.
