A grab bag of nits :)

1. What is the argument to create_random_device_generator_with_token? Is it just any string? Maybe good to document that in README.md

2. In Design section of README.md, " on CPU or CUDA to" -> "on CPU or on GPU using CUDA"

3. In csprng.cu - my_random_kernel_cuda is not a good token

4. Line 93 of aes.cuh - I don't know if the C/C++ standards says that unsigned always means unsigned int - maybe good to be explicit

5. test_geometric has some commented out lines - this maybe tracked in another issue?
