Should this run automatically?

IMO it's fine to run it manually, but there needs to be a README somewhere that
describes what's necessary to set up the database. 

If the database doesn't exist the tests should fail and either point to the
README file or the script.

Added a README.  I'm not sure how to make the error message point back to the
script, since the error would be encountered somewhere down the line when
someone runs sql.Open.  AFAICT there's not an easy way to inject the message at
that point.
