/**@class ObservingList
	*Tool window for managing a custom list of objects.  The window
	*displays the Name, RA, Dec, mag, and type of each object in the list.
	*
	*By selecting an object in the list, you can perform a number of functions
	*on that object:
	*+ Center it in the display (TBD)
	*+ Examine its Details Window (TBD)
	*+ Point the telescope at it (TBD)
	*+ Attach a custom icon or name label (TBD)
	*+ Attach a trail (solar system only) (TBD)
	*+ Open the AltVsTime tool (TBD)
	*
	*The user can also save/load their observing lists, and can export 
	*list data (TBD: as HTML table?  CSV format?  plain text?)
	*
	*The observing notes associated with the selected object are displayed 
	*below the list. (TBD)
	*
	*TODO: 
	*+ Implement a "shaded" state, in which the UI is compressed to
	*  make it easier to float on the KStars window.  Displays only
	*  object names, and single-letter action buttons, and no user log.
	*+ Implement an InfoBox version (the ultimate shaded state)
	*
