Rocket Todo Example
===================
Before running this example, you'll need to ensure there's a database file
present. You can do this with Diesel.
Running migration with Diesel
-----------------------------
Just run the following commands in your shell:
```
cargo install diesel_cli # installs the diesel CLI tools
DATABASE_URL=db/db.sql diesel migration run # create db/db.sql
```
