/**
* Provides user interface objects that combine two or more look and feels. When
* a component asks for its UI, this look and feel returns a multiplexing UI
* that handles all communications with both the default look and feel and one
* or more auxiliary look and feels. For example, if a user combines an
* auxiliary audio look and feel with the Motif look and feel, the
* {@code JButton.getUI} method would return an instance of
* {@code MultiButtonUI}, which would handle both a {@code MotifButtonUI} and an
* {@code AudioButtonUI}.
* <p>

* Using the Multiplexing Look and Feel.</a>
