Create config.js for twitter authentication

> vi lib/config.js
module.exports = {
  consumer_key: 'xxxxxx',
  consumer_secret: 'xxxxxx',
  access_token_key: 'xxx-xxxxx',
  access_token_secret: 'xxxxxxx'
}

Create tweet.js which retrieves trend words
> vi tweet.js

var Twitter = require('twitter');
var config = require('./lib/config.js');

var T = new Twitter(config);

var params = {
  id: 1117099
}

dt = new Date();
dt_format = dt.toLocaleString();

T.get('trends/place', params, function(err, data, response) {
    var tweets = data[0].trends;
    var j = 0;

    for ( i=0; i < tweets.length; i++ ) {
        if ( tweets[i].tweet_volume ) {
            trendData[j] = {"name": tweets[i].name,
                            "query" : tweets[i].query,
                            "tweet_volume" : tweets[i].tweet_volume,
                            "date" : dt_format
                            };
            j++;
        }
    }

    console.log(trendData);

});
