 Changelog

-For Version 1.0:
+Version 1.0:
     -   The "normal" camellia version is used instead of the mini or reference version.
     -   Camellia is now loaded using CFFI. This improves speed and avoids shipped DLLs. It's better than the self-made-on-first-use compilation.
-    -   Supports CTR mode
+    -   Supports all standart modes of operation (ECB, CBC, CFB, OFB, CTR)
