    Description
    ~~~~~~~~~~~

    Settings file, used to configure the main Flask app.

    This configuration provides three classes:

    + :class:`Config` defines attributes for a global behaviour
    + :class:`ProductionConfig` defines and set attributes to use only in a\
            stable environment ( like a loggin level not pushed to extreme )
    + :class:`DevelopmentConfig` defines and set attrs only for a dev environment

    There is also another class, :class:`CloudConfig` contains credentials and\
    url of the favorite cloud providers
