  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).
