Scripts to scrape tweets.

[adiah80]

Add a script to scrape tweets from twitter.

Some basic functionality should include :

• Scraping all the (original) tweets of a user.
• Scraping all the tweets liked by a user.
• Scraping all the tweets retweeted by a user.
• Scraping all the tweets on which a user has commented.
• Scraping all the accounts followed by a user.
• Scraping all the tweets from all the accounts followed by the user.

We would also need functions to update the "tweet database" regularly. This would require some scraping functions that implement the above features after a certain last-saved tweet.

This could be done by adding an optional parameter characterizing the last-saved tweet to the above functions.

Refer to twintproject/twint for some ideas on implementation.
