Description

Provide a place to start adding more structured documentation beyond just the README. Start with an doc/index.rst or whatever the basic tutorial recommends for getting started: https://docs.ros.org/en/rolling/How-To-Guides/Documenting-a-ROS-2-Package.html#configuration

Motivation

Working toward having a design and usage reference, and colocating it with the code makes a lot more sense than splitting into arbitrary tutorials/guides in ros2_documentation. This is the first step to building out that structure.
