042     ** You may explicitly provide a Customizer for your Bean
043     ** class, which allows you complete control of the editing
044     ** of the Bean.<P>
045     **
046     ** A Customizer is meant to be embedded in an RAD tool,
047     ** and thus must be a descendant of <CODE>java.awt.Component</CODE>.<P>
048     **
049     ** It must also have a constructor with no arguments.  This
050     ** is the constructor that will be called by the RAD tool to
051     ** instantiate the Customizer.<P>
052     **
053     ** Over its lifetime, an instance of a Customizer will only
054     ** customize one single Bean.  A new instance of the
055     ** Customizer will be instantiated to edit any other Beans.<P>
056     **
057     ** The Customizer is responsible for notifying its
058     ** PropertyChangeListeners of any changes that are made,
059     ** according to the rules of PropertyChangeListeners (i.e.
060     ** notify the clients <EM>after</EM> the property has
061     ** changed).
