This is a log of changes that the ncurses C++ binding has gonethrough starting with the integration of menu and forms integrationinto the binding.990731  + Improve support for pads. A viewport window may now be added to          a pad. It will then be possible to use a builtin panning mechanism          to view the pad.970908	+ Improve NCursesWindow class: added additional methods to	  cover more ncurses functionality. Make refresh() and 	  noutrefresh() virtual members to allow different implementation	  in the NCursesPanel class.	+ CAUTION: changed order of parameters in vline() and hline() of	  NCursesWindow class.	+ Make refresh() in NCursesPanel non-static, it is now a	  reimplementation  of refresh() in the base class. Added 	  noutrefresh() to NCursesPanel.	+ Added NCursesForm and related classes to support libform	  functionality.	+ Moved most of configuration related stuff from cursesw.h to	  etip.h	+ Added NCursesApplication class to support easy configuration 	  of menu and forms related attributes as well as ripped of	  title lines and Soft-Label-Keys for an application.	+ Support of Auto-Cleanup for a menus fieldlist.	+ Change of return type for current_item() and operator[] for	  menus.	+ Enhanced demo.970502	+ Introduced the THROW and THROWS functions/macros to prepare	  a smoother transition to real exception handling.	+ Exception classes provided in etip.h	+ Added the NCursesMenu class to support libmenu functionality.	+ The inheritace relation between NCursesWindow and NCursesColorWindow	  was kind of brain damage. Monochrome is a special case of colored, so	  the relation should be just the opposite. This would allow all 	  derived classes like NCursesPanel, NCursesMenu or NCursesForm to 	  have colors.	  To resolve that design flaw I put the color functionality into the 	  NCursesWindow class and it can be switched on by the static member	  useColors(). NCursesColorWindow is still there for compatibility	  reasons.
