This update changes templates to work with ACF fields.
For Models implementing the CustomPostType interface, change the customPostTypeData method to a static method from instance method.
If you were using the Template & Sidebar metabox from the TemplateAndSidebarServiceProvider, templates are now handled with WordPress meta. In models implementing the CustomPostType interface, return an array of available templates from the static getAvailableTemplates method. Use the updated SideBarServiceProvider to create a sidebar metabox.
