Create counts for modules by category from nodejs.org module wiki

request('http://github.com/joyent/node/wiki/modules', function(err, res, body) {
  parser.write(body).close();
  var sorted = categories.sort(function(x,y) {
    if (x.name === y.name) {
      return 0;
    }
    else if (x.name < y.name) {
      return -1;
    }
    else if (x.name > y.name) {
      return 1;
    }
  });
  sorted.forEach(function(item) {
    console.log(item.name + ":" + item.modules);
  });
});

Updated now to output sorted.
