//! Minimal regression example
//!
//! This example demonstrates the minimal steps required to run a model
//! comparison using the `RegressionModel` API. It loads a small regression
//! fixture, builds default regression settings, trains all configured
//! algorithms using cross-validation, and prints a comparison table.
//!
//! Run with:
//!
//! ```bash
//! cargo run --example minimal_regression
//! ```
