Country lists

[zverok]

1. All countries list: it seems, should be hardcoded into reality (extracted from Wikipedia with some script, updated on each errrr world situation update), and just grabbed as a list via infoboxer;
2. (Later?) Some specialized country lists (see Wolfram, see Wikipedia categories, and so on), like:
   • G8/G20/UN/other alianses countries;
   • countries by continent
   • ...

Ruby syntaxt for 2 may be like:

# fetch-then-test syntax
Reality.countries.select(&:g20?)
Reality.countries.select{|c| c.continent.name == 'South America'}

# DB-alike query syntax
Reality.countries.where(continent: 'South America').all
