//! This example can be run with the following command:
//!
//! `cat some_interesting_data.json | cargo run --example reader -- --collapse`
//!
//! This example demonstrates parsing json from the [`Stdin`]\(standard input) to a [`JsonTable`].
//!
//! * Check out [`serde_json`] for other helpful ways to import json data into your project.
//! * Check out [`std::env`] and [`std::io`] for more examples of dealing with system streams.
//! * Windows alternatives for the unix `cat` command:
//!     - `type` for command prompt
//!     - `get-content` for powershell
