make mod parser public

[gkorland]

ref #18 exposing the parsing results will allow us to use the ParseTokens to add new paths

[gkorland]

@freestrings can you please merge this PR?
Based on this PR we can write a NodeVisitor and work around issue #18

@gkorland
I have a lot of work these days, so I checked "mail" late.

The parser was developed for module internal use and plans to support joins and functions. this module is likely to change. there are no plans to make it public yet.

@freestrings any other option you might expose this functionality?

[gkorland]

@freestrings that is only way I found to verify a path is static and can return at most one path

I would be interested in the same feature: see #61 #62

As the PR is open for over a year now, with no progress and feedback, I am wondering if this crate is still maintained. I think it is ok, if it is not. But that would be good to know, so I might consider forking and re-publishing the crate myself.

Fixed issue at https://github.com/freestrings/jsonpath/tree/feature/refactoring and will be merged soon.
