Request for a more detailed tutorial of codegen

[Huayan Zhang]

Hi! I'm a new guy to Symforce.

Thanks for your great work!

Currently, I'm really interested in the codegen module. Your website provides a tutorial to generate the Cpp code:
https://symforce.org/tutorials/codegen_tutorial.html

This tutorial is too brief and difficult for me to understand.

Could you please give me some tips about how to use the generated *.h file? How to build a Cpp project using the generated code?

If you can provide a simple project, that will be more friendly to beginners.
