Generating SQL

Okay, typing out SQL is really tedious. Let's do better.

• Connect to the provided db.sqlite3 database. How many users are in the users table?
• What is the SQL command to add a new user to the database? Add yourself using the sqlite console.
• We have a list of new users to add to the database in new_users.csv. Look at script.rb and finish it so that it inserts the users from the file. How many users are there after running the script?

N.B.: under normal circumstances, it's a bad idea to check your database file in to git. Please don't take this as an example.
