    DESCRIPTION: Validates that a string contains only

        4 digit year. Date separator can be ., -, or /.
        Uses combination of regular expressions and 
        string parsing to validate date.
        Ex. mm/dd/yyyy or mm-dd-yyyy or mm.dd.yyyy
        
    PARAMETERS:
       strValue - String to be tested for validity
       
    RETURNS:
       True if valid, otherwise false.
       
    REMARKS:
       Avoids some of the limitations of the Date.parse()
       method such as the date separator character.
