Re-Organisation of the C++, PY Community repos

@chhenning I would be very interested in optimizing the hell of c++ HTM code. Would love to see your changes and merge them into the proposed structure!

I did some performance analysis …do you have a thread about optimization ? If not, can we start one? I 've done

  • some micro-benchmarks
  • considered ditching the hand-made ASM
  • initial test with eigen
  • performance analysis of the HTM chain
