Netlist code refactoring:
- more use of c++ features - some CRTP in pfmtlog - demangled code for truthtables - use more constexpr - rewrite main loop - use default constructors and assignment operators were applicable. - optimized 7448 and 9316 All of this has decreased startup time by approx. 25% to 30%. Complex netlists like pong or kidniki are parsed, analyzed and constructed in around 15 ms. Run performance has increased by about 5%. All in all not to bad. A game like pong uses a clock of 7 MHz (after division by 2). Thats 14 MHz clock invocations. Running at over 200%, 28 MHz. On a 3.9 GHz Machine about 140 cycles/clock change. [Couriersud]
