/**
* Builds consistent button stacks that comply with popular style guides.
* Utilizes the JGoodies {@link FormLayout} and honors the platform's
* {@link LayoutStyle} regarding button sizes, and gaps.
*
* This builder sets a hint for narrow margin for the gridded buttons.
* This can reduce the button stack's width if some buttons have long texts.
* For example, a stack with 'OK', 'Cancel', 'Configure…' will likely
* exceed the minimum button width. The narrow margins help getting narrow
* stacks.
* Note that some look&feels do not support the narrow margin feature,
* and conversely, others have only narrow margins. The JGoodies look&feels
* honor the setting, the Mac Aqua l&f uses narrow margins all the time.
*
* Example:
* The following example builds a button stack with Close, Up and
* Down, where Up and Down are related, and Close is not related
* to the other buttons, which makes a wide gap for the unrelated and
* a smaller gap for the related buttons.
*
* private JPanel createCloseUpDownButtonStack(
* JButton close, JButton up, JButton down) {
* return ButtonStackBuilder().create()
* .addGridded(close)
* .addUnrelatedGap()
* .addGridded(up)
* .addRelatedGap()
* .addGridded(down)
* .build();
* }
