A simple traversal policy that allows this editor panel to control the order that components
get focused when pressing Tab and Shift-Tab.
<P>
Note: We typically do not use traversal policies in the application.  We do so here due to 
the complicated nature of this widget.  It seemed easier to specify the policy than to 
change the order of the widgets in the UI to get the expected traversal order.
<P>
Note: This widget is a bit unusual in that not all focusable components are traversable using
Tab and Shift-Tab.  Specifically, the radio button groups will only have one entry in the 
list of traversal components.  Once one of the radio buttons is focused, the up and down 
arrow keys can be used to navigate the radio buttons.  With this traversal policy, pressing 
Tab when on these buttons will move to the next traversal component.
