+The DateEdit interface provides visual feedback to the user via a pixamp
+to indicate if the assocated GtkEntry box contains a valid date. Green
+means complete and valid date. Yellow means a valid, but incomplete date.
+Red means that the date is not valid, and will be viewed as a text string
+instead of a date.
