- More c++, less macros
* Significantly reduced the use of unused_var and replaced it with
[[maybe_unused]]
* use enum class in ppmf.h
- Changes to testing code in ptest.h
* Catch exceptions in more places
* The verbosity of the output can now be controlled
* Display of test stats totals
- added support for cspell
- fixed various typos
- fixed SUBTARGET=nl build
- fixed more file permissions
- srcclean and add fix_permissions target to netlist makefile
