E.g., discrete would link to examples/example_discrete.py and datasets/spector documentation. And backlinks from the datasets and examples as well (though this isn't always as clear. datasets can be flexible).
link to examples from module docs in merged PR #330 and #396 ( #473 rebased version)
link to dataset and backlinks form examples to module docs missing or not checked
I think the one-way links are good enough for now.
