Rating
======
CloudKitty is shipped with three rating modules:
* ``noop``: Rating module for testing purpose (enabled only).
* ``hashmap``: Default rating module corresponding to usual CloudKitty
use cases (disabled by default).
* ``pyscripts``: Custom rating module allowing you to add your
own python scripts (disabled by default).
You can enable or disable each module independently
and prioritize one over another at will.
* ``Enabled`` state is represented by a boolean value (``True`` or ``False``).
* ``Priority`` is represented by an integer value.
.. note::
The module with the biggest priority value will process data first
(descending order).

Rating module introduction
==========================
There are three rating modules in Cloudkitty now, including the ``noop``,
``hashmap`` and ``pyscripts``. Only the noop rating module is just for
testing. All modules can be enabled and disabled dynamically. Cloudkitty
allows to run several rating modules simultaneously, and the user or
operator can set the priority for a module. The order in which the modules
process the data depends on their priority. The module with the highest
priority comes first.
