DOC: User guide refresh

[martinfleis]

Sorry, this is a bit large PR. I have updated the notebooks in the user guide to use the new API.

Alongside I've noticed few things related to MultiIndex:

• some shape stuff did not work
• tessellation seems to break MultiIndex but I need to have a proper look
• there was a minor issue in verify_tessellation
• get_node_id needs updating to rely in indices like everything else. probably as get_nearest_node

@jGaboardi I think that this is mergeable now. there are some follow-ups but this is already large enough
