v3.0.0

• Change to method signature of HyraxRecordImporter.new
  • initialize method now accepts an attributes hash for
    attributes that come from the UI or importer rather
    than from the CSV/mapper. These are useful for logging
    and tracking the output of an import job for a given
    collection, user, or batch.
• Improved default logging
  • logs are more easily parsed, e.g., by splunk
  • logs contain summary information
  • option to pass in a batch_id to track successes and failures per batch
