    - turned on restrict keyword by default (makes large difference on GPUs)
    - smarter block indexing: changing block size depending on domain size
      Example: previously there where (1,1,1) blocks when requested
      block size was (64, 1, 1) and domain size (1, 512, 512), now the
      block size is changed automatically to (1, 64, 1) in this case
    - added __lauch_bounds__ to kernels to allow better optimizations from
      the CUDA compiler
