            DESCRIPTION: Validates that a string contains only 
                valid dates with 2 digit month, 2 digit day, 
                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.
