Defines an interface for classes which determine the active theme. To set the active theme, create a new service tagged with 'theme_negotiator' (see the theme.negotiator.admin_theme service in user.services.yml for an example). Your service class needs to implement this interface. If you are setting a theme which is closely tied to the functionality of a particular page or set of pages (such that the page might not function correctly if a different theme is used), make sure to set the priority
