Re-arrangement for cleaner database file structure:
- Improved the integration logic between nk and n2 parts of the database.
- Established a clear separation between research data and manufacturers' data.
- Reformatted the "Info" section into YAML format, renamed it to about.yml, and placed it within the main database structure.
- Removed "INFO" paths from catalogs; refer to the appropriate about.yml in the database structure when needed.
