Practically speaking, - * the templates given in the first argument first are prepended with - * the template path (property in this class), then given to - * get_first_file_location for the rest of the processing. - * - * Templates given to this function can be relative paths for templates - * located in subdirectories of the template directories. The paths - * should be relative to the templates directory (template/ by default). - * - * @param string or array $files List of templates to locate.

If true, function will return location where template is - * supposed to be. If false, function will return false. - * @param bool $return_full_path If true, function will return full path - * to template.
