/**
 * Controller for CMS pages. CMS pages are represented by Page instances (i.e. entries of the page database table).
 * The template property of a Page object defines the action method below. If a travel program is assigned then the
 * travelProgramAction is used. If no template is specified, then the defaultAction is used.
 * If there is no action method, the defaultAction is called and the template name is passed as an argument. A twig
 * file with this template will be rendered in this case.
 *
 * The view templates can be found pages/cms.
 *
 * Also see {@link KernelControllerListener}, which handles routing.
