Upfront text about how to cite BOUT++

[ZedThree]

We should have something on the homepage about how to cite BOUT++, preferably with something people can just copy+paste

[bendudson]

Agreed. There are several possible papers; we really need a more recent review paper than https://doi.org/10.1017/S0022377814000816 which has some authors but is notably missing @ZedThree, @JosephThomasParker and @d7919 which I think rules it out. With the latest release and developments in OpenMP and vectorisation, perhaps some kind of software paper could be submitted?

[ZedThree]

I am at a hackday for the Citation File Format, which might provide a solution. It can include additional papers that should be cited as well.

[JosephThomasParker]

Deja vu. This discussion is only allowed when one of us is at a CFF hackday. :)

I'm currently writing up the OpenMP/vectorization changes. If we can't find a journal, STFC does have a technical reports process.

Any chance to get this on the website?
Would be nice if I could just copy paste this :-)

Where should this go? Documentation? Own section?

[johnomotani]

Bump. A list of the Zenodo DOIs would be nice to have too :-)
