Fcs

this adds a bib file for our Simulator folder of zotero. It houses every reference I could find on other nuclear FCSs. it builds on #5.
I understand, and I'm happy to do that if you don't want to bother. It's just that these question marks will keep reappearing every time you re-export unless you fill in the year in zotero. If you make additions to the zotero folder and re-export, then we'll have this missing data in the bib again... that's all.
