Detailed Description

Minimal tabular container with column-wise storage and CSV I/O.

This header provides a lightweight DataFrame type inspired by common data-analysis libraries. It stores columns as Series<T>, indexed by column name, and supports:

• row/column access,
• simple statistics and summary,
• CSV export,
• optional labeled index.
