"""
To run an import you combine two classes; one each of:

- RecordSource: somehow iterates over a source of raw records (eg, from a
  database, Kafka, files on disk, stdin) and pushes into an entity importer.
- EntityImporter: class that a record iterator pushes raw (unparsed) records
  into. The entity importer parses and decides what to do (ignore, update,
  insert, etc). There is usually a primary entity type, though related entities
  can be created along the way. Maintains API connection and editgroup/batch
  state.
