Add country regions, provinces, cities and related infos

[mdesantis]

It would be wonderful if it would be possible to retrieve regions, provinces and cities.

Something like:

// Regions of country
// /rest/alpha2/it/regions ->
{ regions:  [ "Abruzzi e Molise",
              "Basilicata",
              "Calabria",
              "Campania",
              "Emilia-Romagna",
              "Friuli-Venezia Giulia",
              "Lazio",
              "Liguria",
              "Lombardia",
              "Marche",
              "Piemonte",
              "Puglia",
              "Sardegna",
              "Sicilia",
              "Toscana",
              "Trentino-Alto Adige",
              "Umbria",
              "Valle d'Aosta",
              "Veneto" ] }

// Provinces of region
// /rest/alpha2/it/regions/Veneto/provinces ->
{ provinces: [ "Verona", "Venezia", ... ] }

// Cities of province
// /rest/alpha2/it/regions/Veneto/provinces/Venezia/cities ->
{ cities: [ { name: "Venezia", zip_codes: [ "30121", ... , "30176" ] }, 
            { name: "Chioggia", zip_codes: [ "30015" ] },
            { name: "San Donà di Piave", zip_codes: [ "30027" ] }, 
            ... ] }

// Cities of country by name
// /rest/alpha2/it/regions/Veneto/provinces/Venezia/cities ->
{ cities: [ { name: "Venezia", zip_codes: [ "30121", ... , "30176" ] }, 
            { name: "Chioggia", zip_codes: [ "30015" ] },
            { name: "San Donà di Piave", zip_codes: [ "30027" ] }, 
            ... ] }

Cities could have metadata like f.i. zip codes, which are very useful.

It is a huge work because recording and maintaining the whole list of regions, provinces and cities for every world country is hard, but it is a good target to be accomplished by an open source project.

yes this looks like smth that can be done in the future. thanks for the advice. the data comes from https://github.com/mledoze/countries, so i'll forward this there. but i might start using my own forked version.
