- Dead code removal and minor refactoring. - Simplify. Align naming with stl. Fix somed pedantic warnings. - More STL compatability. - Remove ATTR_HOT and ATTR_COLD. Refactored netlist_time. - Fix long standing workaround which would ignore policy of change-only" propagation. - Rewrote for loops to use auto : semantics. - Truthtable cleanup. (nw) - Get rid of nl_math. Remove nl_util.h and moved contents to plib/putil.h. - Fix standalone build. Refactor ptypes.h. [Couriersud]
