-/**
- * Database backend class for storing objects in locally created files.
- *
- * This class serializes arrays stored in the dataset instance and saves them
- * to local files. Every file (except 'info') represents a single line. Every
- * directory within the 'db' (base) directory represents a table.
- *
- * A configurable 'file_io_class' is being used as "storage backend".
