/**
* This function handles the configuration inheritance for the synchronization.
* The function handles the inheritance over a recursive call.
*
* First this function is called with the theme which should be synchronized.
* If the theme uses a inheritance configuration, the
* function resolves the theme parent and calls the "createConfig" function
* of the Theme.php.
* The Form\Container\TabContainer won't be initialed again, so each
* inheritance level becomes the same container instance passed into their
* createConfig() function.
*
* This allows the developer to display the theme configuration of extened
* themes.
*
* @param Theme $theme
* @param Form\Container\TabContainer $container
* @return Form\Container\TabContainer
