 * expects a reference to a method that consumes a single {@link FileHandle} or an {@link Array} of files. File chooser
 * allows to select files (not directories). If the file chooser is cancelled, file handle-consuming method will receive
 * null; array-consuming method will receive empty array. Mapped to "fileChooser".
