Title: Hello World Tutorial | Context-Generic Programming

Open Graph Title: Hello World Tutorial | Context-Generic Programming

Description: In this tutorial, we will build a small working program that greets people by name, using CGP's core features. Along the way we will encounter CGP functions, implicit arguments, struct-based contexts, and HasField derivation. By the end you will have seen a complete working example and will understand at a high level how CGP leverages Rust's trait system to let you write highly reusable code without any runtime overhead.
