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