RandomNumberGeneratorFactory nows uses Clone instead of Creator pattern.

  • requires CodePatterns 1.0.4.
  • RandomNumberGenerator_Encapsulation implements clone() with calls the constructor ...
  • ... who in turn (sadly) needs some evil dynamic_cast to get the complex type from the simple interface, because we need access to true engine and distribution. The instances themselves are obtained properly from the respective factories. However, the constructor is protected now.
  • FIX: friend classes can actually be forward declared.
  • Property mode set to 100644
