List all chirps

Let's work on the index, where we list all our Chirps for our users.

URI Pattern	Controller#Action	What should it do?	Example action code
/chirps(.:format)	chirps#index	Show a list of all the chirps on the page	`Chirp.all`

In app/controllers/chirps_controller.rb in between def index and the closet end, let's add

  @chirps = Chirp.all

like so:

In the corresponding view --app/views/chirps/index.html.erb, let's add this line:

<h1>All Chirps</h1>
<% @chirps.each do |chirp| %>
  <p><%= chirp.body %></p>
  <p>
    - <i><%= chirp.author %></i>
  </p>
<% end -%>

Now if we go to http://localhost:3000/chirps again, we'll see:

Pretty nifty!

Discuss with the coach. What did we just do? What did the controller do? What did the view do?
