Override URI field in TastyPie

uri_resource.py

'''
Usage:

    class MyResource(CustomURIResource):
        class Meta:
            queryset = User.objects.all()
            resource_name = 'user'
            url_field = 'username'

Will make accessible URIs like so:

    /api/v1/user/<username>/

and produce them from list and detail views.
