  42  ** You may explicitly provide a Customizer for your Bean
  43  ** class, which allows you complete control of the editing
  44  ** of the Bean.<P>
  45  **
  46  ** A Customizer is meant to be embedded in an RAD tool,
  47  ** and thus must be a descendant of <CODE>java.awt.Component</CODE>.<P>
  48  **
  49  ** It must also have a constructor with no arguments.  This
  50  ** is the constructor that will be called by the RAD tool to
  51  ** instantiate the Customizer.<P>
  52  **
  53  ** Over its lifetime, an instance of a Customizer will only
  54  ** customize one single Bean.  A new instance of the
  55  ** Customizer will be instantiated to edit any other Beans.<P>
  56  **
  57  ** The Customizer is responsible for notifying its
  58  ** PropertyChangeListeners of any changes that are made,
  59  ** according to the rules of PropertyChangeListeners (i.e.
  60  ** notify the clients <EM>after</EM> the property has
  61  ** changed).
