libwy.0.68.9 is released

https://sourceforge.net/projects/cscall/files/libwy-0.68.9.tgz/download
libwy is a C++ library. Added features of this release:

1. Xn-Stream.
  Xn-Stream is a general format of byte stream sutible for almost all forms of
  communication, scripts, configure files, or binary files. Xn-Stream is added
  into this elementary C++ library because of this omni-capability and the
  simplicity fits the efficiency principle of libwy. See Wy.Xn-Stream(3wy).

2. Artificial Neural Network
  The implement uses only CPU (not really bad for the 1st version, besides many
  platforms and the final product have just CPU). ANN in C++ (class) is very
  flexible. Comparing with nowadays AI kits, ANN in classes enable programs to
  implement (with Xn-Stream) various kind of AN network easily. See Wy.ANNet(3wy).
-----

PS. I think C might support Xn-Stream and ANN as basic 'system' component in
   the future. For ANN, there are lots of O(2^N) problems. GPU (or whatevev)
   would become the norm of PC computation model). For Xn-Stream, just likely.
   Of course, deficiency report and suggestions are welcome.
