Modeling Twitter

twitter.rb

#The goal of this exercise is to create the models for a app like Twitter. We are not going to use Rails, just plain old Ruby.
#The goal is to be able to generate timelines for each user. The final code should look like this:


twitter = Twitter.new

user1 = User.new("alice")
user1.tweet("hello world")
user1.tweet("So hungry today")

user2 = User.new("bob")
user2.tweet("Its a nice day")
user2.tweet("Yay for ice cream")

user1.follow(user2)

user1.get_timeline #should return an array of strings of bobs tweets since user1 only follows user2
