Initial example of date picker using a menu button pattern

Link to datepicker menu button example:
https://raw.githack.com/w3c/aria-practices/issue34-date-picker-examples/examples/datepicker/datepicker-menubutton.html

Issues:

  1.  Other menu button date pickers move focus to the textbox instead of the button when a date is picked, we still want to stick with focus returning to the button?
  2.  Other examples:
