[joss] Can HNX represent isolated nodes?

[szhorvat]

Until #137 is answered, I'll just ask questions here. I hope that's okay.

Can HNX represent isolated nodes? If yes, how can I construct a hypergraph with isolated nodes? If not, can you point to the section of the docs that explains this? I'm sure I'm missing something.

I noticed that when removing edges using .remove_edges() (docs missing), nodes with no remaining incident edges also disappear.

The current version of HNX does not support representing isolated nodes. This may be a feature in a future version.

Is this mentioned in the documentation or tutorials? If not, it would be nice to clarify it.
