041/**
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).
