HTML docs for C++ implementation

[hickford]

Hi. I found the docs for the CEL spec at https://github.com/google/cel-spec/tree/master/doc . Is there any further documentation for this C++ implementation beyond the code comments in header files? And can I browse the API in doxygen-style reference documentation anywhere?

Ideally similar to how Protocol Buffers has generated HTML documentation for the C++ API https://developers.google.com/protocol-buffers/docs/reference/cpp

A doxygen style reference, or a port of the CEL Go Codelab would be very useful for C++ but we don't yet have such references. I'll be sure to ping this bug when I do.

codelab seems to be added by now https://github.com/google/cel-cpp/tree/master/codelab

Could a link to codelab documentation be added to readme? We had hard time finding it, in a bit unexpected place https://github.com/google/cel-cpp/blob/master/README.md
