//This class is used to display data on the StandardDialog or Tabbed Dialog class.   Essentially,
//all node/edgeClickListeners return an object of  type ActivePanel with the function
//GetProprietaryNode/EdgeInfoPanel(), which is called every time a node/edge
//is clicked.  Each of the ActivePanels is successively added to the tabbedPane
//on the TabbedDialog.  That way, we can plug-and-play PacketAnalyzers and not have to worry about
//updating the display code.  Each Packet Analyzer carries its display info
//with him in the form of an Active Panel
//**************************************************************************
//**************************************************************************
//This is how the function GetProprietaryNodeInfoPanel() works:
// 1.  if GetProprietaryNodeInfoPanel() returns null, that PacketAnalyzer 
//	will not have any information displayed on the PropertyDialog
// 2.  if GetProprietaryNodeInfoPanel() returns an ActivePanel with
//	the variable cancelInfoDialog set to TRUE, the PropertyDialog will
//	not be displayed at all, for any packetAnalyzer.
// 3.  If GetProprietaryNodeInfoPanel() returns a valid ActivePanel, it will
//	be displayed as a panel on it's own tab in the JTabbedPane of the 
//	PropertyDialog.  The tab with be set with tabTitle.
//**************************************************************************
//**************************************************************************
//The gist of an active panel is:
// 1.  It has a variable cancelInfoDialog which cancels the displaying of
//	the entire PropertyDialog
// 2.  It has a variable tabTitle, which will be the name on the tab
//	which displays this ActivePanel
// 3.  The Active Panel itself is a JPanel, which will be displayed on a separate
//	tab on the PropertyDialog
// 4.  It has a function UpdateDisplayVariables, which sets the components
//	on the panel to their apropriate values.  This is called to initialize
//	the panel 
// 5.	 It has a function Apply Changes which should take the values on the
//	components and assign them to the variables to which they correspond.
//	This function is called when the "Apply" button is hit on the dialog.
//**************************************************************************
//**************************************************************************
//A good way to create one of these is to create the display using visual cafe
//or some other editor.  Then copy the code into you packet analyzer class,
//write the InitializeDisplayValues and ApplyChanges functions, and you are done.
//You should probably pass the node/edgeInfo class into the active Panel in 
//the constructor to facilitate the InitializeDisplayValues and ApplyChanges functions.
//You also may want to run the Active Panel as a seperate thread to continuously
//update the values in the display as the network runs and the values change.
//**************************************************************************
//**************************************************************************
//If you want actions to be performed immediately when the user changes the value
//of a component on the display, use the ActionPerformed, ItemStateChanged, and
//StateChanged functions to handle events generated from the components
