* @author gwg
*
* This class provides the display components for handling Date data types,
* specifically SQL type DATE.
* The display components are for:
* <UL>
* <LI> read-only display within a table cell
* <LI> editing within a table cell
* <LI> read-only or editing display within a separate window
* </UL>
* The class also contains
* <UL>
* <LI> a function to compare two display values
* to see if they are equal. This is needed because the display format
* may not be the same as the internal format, and all internal object
* types may not provide an appropriate equals() function.
* <LI> a function to return a printable text form of the cell contents,
* which is used in the text version of the table.
* </UL>
* <P>
* The components returned from this class extend RestorableJTextField
* and RestorableJTextArea for use in editing table cells that
* contain values of this data type. It provides the special behavior for null
* handling and resetting the cell to the original value.
