A small falcon hook to parse sorting elements from the request.

Usage
-----

The easiest way to use this hook is the following:

.. code:: python

    @falcon.before(SortingHook())
    def on_get(self, req, resp, user):
        # Here req['context']['order'] is set

The Hook will look in the query parameters for parameters looking like :code:`sort=value`.

The default sorting order is ascending.
In order to sort in a descending order a minus (:code:`-`) sign needs to be specified before the value.
i.e. :code:`sort=-value`

It is possible to specify multiple ordering values by separating them with a comma.
i.e. :code:`sort=-value1,value2`

It will create a list in the request context accessible at :code:`req.context['order']`.
This list consists of tuples where the first element is the name of the field to sort on
and the second the order to follow (either :code:`ASC` or :code:`DESC`)

i.e. :code:`[('foo', 'ASC'), ('bar', 'DESC')]`.

Configuration options
---------------------

One parameter can be passed to the hook:

* sort_query_key : The name of the key used in the query to sort data. Default: :code:`sort`.

Example:

.. code:: python

    @falcon.before(PaginationFromRequestHook(
        sort_query_key='order',
    ))
    def on_get(self, req, resp, user):
        # Get request
