Documentation missing for watts_strogatz_hypergraph

[tlarock]

I was looking at the generators module and noticed that there is no documentation for watts_strogatz_hypergraph. While reading the source is enough to broadly understand the generation process, I am not familiar with the origins of this model, so it would be helpful to add a description and reference. It may also be useful to give the parameters more meaningful names (or just explain that they are inputs to ring_lattice, plus a rewire probability).

Thanks for bringing this up, @tlarock! I believe that @leotrs wrote this function. Leo, do you have a reference for this?
