# Spindate 
# ----------------------------------------------------------------------
# Implements a Date spinner widget.  A date spinner contains three
# Spinner widgets:  one Spinner for months, one SpinInt for days,
# and one SpinInt for years.  Months can be specified as abbreviated
# strings, integers or a user-defined list.  Options exist to manage to 
# behavior, appearance, and format of each component spinner.
