  all tests passes, but there are several questions (left in the source code)
add test cases for WWM-110 requirements.
  Note: new tests will fail.
URL-decode date component of Archival-URL request before parsing, so that "2010%2A" works the same as "2010*".
  added DateUrlPathRequestParser class for common code.
  added static constructor methods to WaybackRequest for cleaner code.
