AccessExpirationDecorator adds an expiration method to values so that they can be used with the UniqueAccessExpireCache { public: AccessExpirationDecorator(): _value(), _span() { }

          AccessExpirationDecorator(const TArgs& p, const Poco::Timespan::TimeDiff& diffInMs):
  
Creates an element that will expire in diff milliseconds _value(p), _span(diffInMs*1000) { }

          AccessExpirationDecorator(const TArgs& p, const Poco::Timespan& timeSpan):
  
Creates an element that will expire after the given timeSpan _value(p), _span(timeSpan) { }
