We're going to be build a simple messaging system using Sinatra. We'll be writing out a POST request and handling the data posted to display it in an ERB file.

1. The contents of bin/post_message.rb must submit a POST request to localhost:9292. It should post the to, from, and content variables along with the request. Lookup how to submit POST requests using net/http and how to submit data along with that request.

2. You will have to have 2 terminal windows open: one for the server to be running (via running rackup) and one for running the binary bin/post_message.rb. Remember to run ruby bin/post_message.rb.

3. We want to persist the data collected from the POST request, so edit the migration. To migrate to the database, check out the Rakefile which defines some helpful tasks.

4. Build out the post '/' route in app.rb to take the incoming data and create a message that persists to the database.

5. Edit views/messages.erb to iterate through all the @messages and display the data.

6. When you visit the '/' route via the get request, you should see your message!

There are no tests. Just make it work.
