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