        @brief Child class of ConfigFile, used to store the settings of the game.

        In addition to ConfigFile, this class provides an interface to manipulate the settings
        with console commands and to cache entries in instances of ConfigValueContainer.

        SettingsConfigFile is a Singleton, meaning there's only one instance of this class
        (and thus only one config file that stores settings).
