/** The wrapper class is a JPanel that wraps a JComponent that implement
 *  TagBehavior. The point of wrapping it is that we can change the
 *  component represented on some UI without changing the container. That
 *  is, the container knows about the wrapper, but not about what's in it.
 *  Consequently, we can change the contents of the wrapper without
 *  affecting the container.
