QuTiPv5 Paper Notebook: smesolve

[Langhaarzombie]

Adds an example notebook for the smesolve solver mentioned in the paper for QuTiPv5.

A far as I can tell, there is only thing left to do:

• Add tests for the notebook (it's not yet clear what exactely to test)
• Include references and format like this

Thank you, Max! Two more general comments (that maybe you have talked about already, sorry):

• I was wondering if these paper examples should go into a separate folder? But the whole structure of the tutorial notebooks could use a bit of a revision...
• Should we wait with merging these PRs until after publication of the paper? I wonder if the journal will make us trouble if the material is "already published". On the other hand, after the paper publication, could there be copyright issues?

yeah we went back and forth on this a bit a few weeks ago. we ended up with this convention of highlighting in their names that they come from the paper, but putting them in the subfolder most associated with their application, e.g., time evolution, qip etc, and then revisiting the whole folder structure later (mostly motived by this qutip.org tutorials page structure problem, which needs some improvement)

hmm fair point. also relates to what we do with the original python files, and where/how we store those. i am not really sure.

Looks good from my side (however, let's wait with merging)
