Date editing module for GRAMPS.
The DateEdit.DateEdit provides visual feedback to the user via a pixamp
to indicate if the associated GtkEntry box contains a valid date. Green
means complete and regular date. Yellow means a valid, but not a regular date.
Red means that the date is not valid, and will be viewed as a text string
instead of a date.
The DateEdit.DateEditor provides a dialog in which the date can be
unambiguously built using UI controls such as menus and spin buttons.
