This supports two use cases for using tsvector_field:
1. Configure your Django project to use tsvecotr_field's DatabaseSchemaEditor
directly by creating your own DatabaseWrapper and referencing
tsvector_field.DatabaseSchemaEditor in the SchemaEditorClass attribute.
See: tsvector_field/schema.py for more info.
2. Just add `tsvector_field` to your project's INSTALLED_APPS setting and this
will use the `pre_migrate` mechanism. Note: `pre_migrate` is not fired for
./manage.py migrate --run-syncdb. So if you are building apps without migrations
you will have to use the more reliable approach in option #1.
