Hello,
   Thanks for your kind words.  The country calling codes are NOT yet
included. Try to get the country calling codes, currencies, and other
codes added soon depending on demand and usage. Still early and rough.
  Cheers.

PS: If you want to help out adding the codes. The source for the
worldlite gem are just plain text fixtures - for "extra" codes it's
key value pairs (in .yml) e.g.

at: +43
de: +42
and so on.   See the world.db [1] for details.
