/**
 * Field for uploading single or multiple files of all types, including images.
 *
 * <b>Features (some might not be available to old browsers):</b>
 *
 * - File Drag&Drop support
 * - Progressbar
 * - Image thumbnail/file icons even before upload finished
 * - Saving into relations on form submit
 * - Edit file
 * - allowedExtensions is by default File::$allowed_extensions<li>maxFileSize the value of min(upload_max_filesize,
 * post_max_size) from php.ini
 *
 * <>Usage</b>
 *
 * @example <code>
 * $UploadField = new UploadField('AttachedImages', 'Please upload some images <span>(max. 5 files)</span>');
 * $UploadField->setAllowedFileCategories('image');
 * $UploadField->setAllowedMaxFileNumber(5);
 * </code>
