Support for circular structures

[pcafstockf]

While JSON doesn't support circular structures, this project's description "... selectively extract data from JSON documents (and JavaScript objects)." does include "JavaScript objects". :-)

In my case, a hacked replacement of JSONPath.prototype._walk served my needs (searching an AST) and allowed me to use this great library.
However, more flexible/official support would be nice.

I'm facing this issue as well, and getting
