Deletion of Europan

Comment: Not seeing a lot of evidence of  here.  Just on book sources there is https://books.google.co.uk/books?id=Lzt7BgAAQBAJ ''Global Gentrification'' which, although Europan is tangential to the subject of the book, or even the chapter, discusses it over several pages.  https://books.google.co.uk/books?id=WFj5KCpmqFwC ''Housing + Single-Family Housing'' discusses several Europan projects.  https://books.google.co.uk/books?id=SDpPAAAAMAAJ ''Europan 6'' is a book about the Dutch entries, and I ''think'' is independent of the Europan organisers, Likewuse https://books.google.co.uk/books?id=GDBUAAAAMAAJ ''Europan 8 in Nederland''.  And https://archinect.com/news/bustler/6213/the-winners-of-europan-14-imagine-productive-cities-across-europe here's a news article.  There's probably a lot more, but I don't think I really need to look any further
Stance: keep
