Support for results as path

[jcoyne]

The javascript jsonPath tool can support results as values or paths:
So that when we're using the data:

{
  "phoneNumbers": [
    {
      "type"  : "iPhone",
      "number": "0123-4567-8888"
    },
    {
      "type"  : "home",
      "number": "0123-4567-8910"
    }
  ]
}

and you query:

jsonPath(o, "$.[*].type")

you get the expected results:

[
  "iPhone",
  "home"
]

If you run the very same query, with the path result type, you see where these results came from:

jsonPath(o, "$.[*].type", {resultType:"PATH"})

[
  "$['phoneNumbers'][0]['type']",
  "$['phoneNumbers'][1]['type']"
]

You can see this feature in action here: http://jsonpath.com/

I find that I am in need of this feature, because I often want to do "give me the parents of the children that match this expression", which is something XPath can do, but JSONPath does not. Getting the paths is an easy way to work around a shortcoming.
