Add @this modifier 
This modifier returns the current element as-is and can be used
to retrieve the JSON document itself. It is equivalent to the `#/` JSON Pointer.

Closes #149

tidwall 5c2e4b3824 Fixed modifier pipe issue 
This commit fixes an issue where chaining modifiers that used a
string arg would fail to process the modifier following the first.

tidwall 1e964df7d9 Support subqueries 
It's now possible to do a query like

  topology.instances.#(service_roles.#(=="one"))#.service_version

On a JSON document such as

  {
    "topology": {
      "instances": [{
        "service_version": "1.2.3",
        "service_roles": ["one", "two"]
      },{
        "service_version": "1.2.4",
        "service_roles": ["three", "four"]
      },{
        "service_version": "1.2.2",
        "service_roles": ["one"]
      }]
    }
  }

Resulting in

  ["1.2.3","1.2.2"]

tidwall 3b5bf6bb5e Added Subselectors 
It now possible to select multiple independent paths and join
their results into a single JSON document.

For example, given the following JSON

    {
      "info": {
        "friends": [
          {"first": "Dale", "last": "Murphy", "age": 44},
          {"first": "Roger", "last": "Craig", "age": 68},
          {"first": "Jane", "last": "Murphy", "age": 47}
        ]
      }
    }

The path `[info.friends.0.first,info.friends.1.last]` returns

    ["Dale","Craig"]

Or path `{info.friends.0.first,info.friends.1.last}` returns

    {"first":"Dale","last":"Craig"}

You can also rename Object members such as

`{"alt1":info.friends.0.first,"alt2":info.friends.1.last}` returns

    {"alt1":"Dale","alt2":"Craig"}

Finally you can combine this with any GJSON component

`info.friends.[0.first,1.age]` returns

    ["Dale",68]

This feature was request by @errashe in issue #113.

tidwall 1ed2249f74 Added modifiers and path chaining 
A modifier is a path component that performs custom processing on
the json.

Multiple paths can be "chained" together using the pipe character.
This is useful for getting results from a modified query.

See the README file for more information.

Josh Baker ba784d767a Fix string output for large integers 
This fix makes calling String() on a JSON Number return the original value
as it was represented in the JSON document for signed and unsigned integers.
This ensures that very big (plus-53bit) integers are correctly returned.
Floating points maintain their previous behavior [-+]?[0-9]*\.?[0-9]*.

Josh Baker a2f35b522e Added support for JSON Lines 
Added support for JSON Lines (http://jsonlines.org) using the `..` prefix.
Which when specified, treats the multi-lined document as an array.

For example:

```
{"name": "Gilbert", "age": 61}
{"name": "Alexa", "age": 34}
{"name": "May", "age": 57}
{"name": "Deloise", "age": 44}
```

```
..#                   >> 4
..1                   >> {"name": "Alexa", "age": 34}
..3                   >> {"name": "Deloise", "age": 44}
..#.name              >> ["Gilbert","Alexa","May","Deloise"]
..#[name="May"].age   >> 57
```

Josh Baker c784c41781 Allow parsing of large integers 
This commit fixes an issue in which GJSON was not representing integers
correctly that were greater than 53-bits when calling the result.Int()
and result.Uint() functions. This happened because GJSON stored all
numbers as float64s in the result.Num field, and Int()/Uint() would
simply try to convert the float64 to int64/uint64 by issuing
int64(result.Num) or uint64(result.Num) operations.

Now rather than a simple cast, GJSON checks to see if the float64 is a
whole integer and if the integer can fit within 53-bits. If so, then
the cast method can be used. Otherwise GJSON attempts to parse the
result.Raw directly. If that fails too, it falls back to the original
method.

This fix should maintain compatibility with existing applications.

thanks @joelpresence for reporting
