Cell editor for editing dates using the jaret datechooser. Supports java.util.date and JaretDate. The fieldidentifier used for the datechooser (see Javadoc there) is not locale dependant (Day/Month/year) have to be changed when used in another country (or removed!).

Key bindings: TAB and CR will leave the datechooser (positive). ESC will leave the chooser resetting the date to the value present when editing started.
