//! A first look at `matten`: create, add, reshape, and inspect a tensor.
//!
//! Run: cargo run --example 00_quickstart
//!
//! `matten` is the family car of Rust tensor libraries — easy to start,
//! no type puzzles, and honest about performance. For heavy numerical work,
//! migrate your flat data to `ndarray`, `nalgebra`, or `candle`.
