 * Simple Pane with line border and title on the top-left corner

 * N.B. this is a limited function replacement for ControlsFX's Borders class, i.e.
 * {@code Node node = Borders.wrap(content).lineBorder().title(getName()).build().build(); }
 * that when used in larger layouts causes infinite JavaFX layout loops.
