public final class HeaderGroup
extends java.lang.Object
 The intent here is that, rather than adding the components under a header
 to a JPanel or other container, you associate them with a HeaderGroup
 instead (in much the same way that ButtonGroup works
 for toggle buttons). This gives you the freedom to have a single layout
 across all collapsable regions.
