Documentation for h5pyd #112
Description
Other than the readme there hasn't been any real documentation for h5pyd. To some extent this is alleviated by just using the h5py docs (https://docs.h5py.org/en/stable/), but there are enough differences (h5py features not supported in h5pyd, h5pyd features not available in h5py) that it would be nice to have an independent set of docs.
