A small example application using Rust, WASM, and Yew meant as a reference and scaffold for other projects.

This application just makes a grid of clickable squares that can then be reset. The code has an example of 2 levels of hierarchy:

App -> Grid -> Cell

Trying to adhere to best practices: the information from parent to child components flow "down" through props and, callbacks send messages "up" from children to parent components.
