 <P>
 Editable viewer for displaying and editing requests and responses.
  <p>
  This abstract class is intended to be subclassed only by clients
  to extend the <code>contentViewers</code> extension point.
  The subclass must have a public 0-argument constructor, which will be used
  automatically to instantiate the viewer when required.
  Once instantiated, <A HREF="../../../../../../org/eclipse/wst/internet/monitor/ui/ContentViewer.html#init(Composite)"><CODE>init(Composite)</CODE></A> is called to create
  the viewer's controls. Then <A HREF="../../../../../../org/eclipse/wst/internet/monitor/ui/ContentViewer.html#setContent(byte[])"><CODE>setContent(byte[])</CODE></A> is called,
  one or more times, to cause the viewer to display particular
  content. Finally, when the viewer is no longer needed, <A HREF="../../../../../../org/eclipse/wst/internet/monitor/ui/ContentViewer.html#dispose()"><CODE>dispose()</CODE></A>
  is called to free up any resources tied up by the viewer.
  </p>
  <p>
  [issue: It's unclear how these content viewers are used.
  Is it just that the UI provides a list of available
  views for the user to make a manual selection from, regardless
  of the actual content of the message traffic?]
  </p>
  [issue: CS - If a ContentViewer is editable, does that mean we can edit the
  bytes of the message and resend it across the wire?  How is an editable ContentViewer
  handled differently by the framework? Perhaps an example of what an editeable viewer would do. ]
