This file never worked, it caused a circular import loop since it attempts to `from bakerydemo.settings.dev import *` but the dev settings does:
```python
try:
from .local import * # noqa
except ImportError:
pass
```
Fixed the `setup.sh` script to set the correct settings module environment variable
Fixes#68
* Update the README with instructions on getting bakerydemo to use the PostgreSQL database from the adjacent container
* Corrected formatting in README
* Automated setting up bakerydemo to use the postgres service from our docker-compose
