- Enable printing of RadixTree debug information: The `debug_db` and
`print_tree_from_node` functions now print detailed information
about the RadixTree's internal structure, aiding in debugging. This
improves the developer experience by providing better tools for
understanding and troubleshooting issues within the RadixTree.
- Remove unnecessary comments: Unnecessary comments in the `debug_db`
function have been removed to improve code clarity.
- Adds a new virtual file system (VFS) implementation for calendar data.
- The calendar VFS provides a read-only view of calendar events,
organized by calendar, date, title, and organizer.
- Includes new modules for factory, model, and implementation details.
- Adds unit tests to verify the functionality of the calendar VFS.
