Hi, first of all thank you very much for this crate, helped me a lot.

I recently had to implement something where I had a bunch of partial json objects, each with its associated json path, and I had to build a json object from all those partial ones. In order to do this I had to parse each json path backwards in order to build my final json object. My code lies here.

But traits for doing this are not public. In the end, I would love to have those public use jsonpath_lib::{ParserNodeVisitor, ParserTokenHandler, ParseToken, StrRange};. I get that it is not the main purpose of the crate ; it is not aimed at being a parser.

I am willing to open a PR for that, I just wanted to have your consent (and explain why). WDYT ?

Thank you very much
