Added function returning ISO 3 country code

[maximeloizeau]

I needed the country code in ISO 3 format so I just added a simple function.

I didn't know if I should use a external json file or internal variable to store the ISO2-ISO3 mappings, feel free to comment about it.

A variable is fine, but could you please reformat so that it's not one long line but lexically-ordered, line-delimited per country along with the country name? As in:

var ccISO2toISO3 = {
  ...
  "BD": "BGD", // Bangladesh
  ...
};

Here's code to help you extract the data from Wikipedia:

// npm install request cheerio
var request = require('request'),
    cheerio = require('cheerio');
request('https://en.wikipedia.org/wiki/ISO_3166-1_alpha-3', function (err, res, body) {
  var $ = cheerio.load(body);
  var $table = $('table > tr > td > tt:contains("ABW")').closest('table');
  var $countries = $table.find('tr');
  var iso3codes = {};
  $countries.each(function (i, el) {
    var $el = $(el);
    var iso3code = $el.find('tt').text();
    var name = $el.find('a').text();
    iso3codes[iso3code] = name;
  });
  console.log(iso3codes);
});

Thanks. I edited the variable as you requested.
