Extensions for JSONPath RW

This extensions will be proposed `upstream <https://github.com/kennknowles/python-jsonpath-rw>`__
and will stay here only if they are refused.

Quick Start
-----------

At the command line::

$ pip install jsonpath-rw-ext

Or, if you have virtualenvwrapper installed::

$ mkvirtualenv jsonpath-rw-ext
$ pip install jsonpath-rw-ext


Extensions

+--------------+----------------------------------------------+
| name | Example |
+==============+==============================================+
| len | - $.objects.`len` |
+--------------+----------------------------------------------+
| sorted | - $.objects.`sorted` |
| | - $.objects[\\some_field] |
| | - $.objects[\\some_field,/other_field] |
+--------------+----------------------------------------------+
| filter | - $.objects[?(@some_field > 5)] |
| | - $.objects[?some_field = "foobar")] |
| | - $.objects[?some_field > 5 & other < 2)] |
+--------------+----------------------------------------------+
| arithmetic | - $.foo + "_" + $.bar |
| (-+*/) | - $.foo * 12 |
| | - $.objects[*].cow + $.objects[*].cat |
+--------------+----------------------------------------------+

About arithmetic and string
---------------------------

Operations are done with python operators and allows types that python
allows, and return None if the operation can be done due to imcompatible types.

When operators are used, a jsonpath must be be fully defined otherwise
if jsonpath-rw-ext can't known if expression is a string or a jsonpath field,
it will choice string.

Example with data::

{
'cow': 'foo',
'fish': 'bar'
}

| **cow + fish** returns **cowfish**
| **$.cow + $.fish** returns **foobar**
| **$.cow + "_" + $.fish** returns **foo_bar**
| **$.cow + "_" + fish** returns **foo_fish**

About arithmetic and list
-------------------------

Arithmetic can be used against two list if they have the same size.

Example with data::

{'objects': [
{'cow': 2, 'cat': 3},
{'cow': 4, 'cat': 6}
]}

| **$.objects[\*].cow + $.objects[\*].cat** returns **[6, 9]**
