1e7e7a214d Simplify the implementation of format and parse:
* For format, all a type must do is implement to_stream.

* For parse, each type X must specialize parse_manip<X,CharT,Traits>.
  Each specialization must include a public typedef to itself named
  type.

* Each parse_manip specialization must have a stream extraction
  operator.

* This commit depends on expression-SFINAE.  If this commit breaks
  your build, it is likely that your compiler/version does not
  support expression-SFINAE.  To fix this NO_EXPRESSION_SFINAE
  needs to be defined in the configuration area of date.h for
  that compiler/version.
