- Removed trampolines (OUTLOGIC, INPLOGIC and friends). - Started using doxygen comment and documentation style. Added doxygen files to documentation folder. - Refactored code triggered by doxygen output. - Moved internal and support classes into namespace detail. - Use an anordered map in parser. - -Wconversion fixes - All done now. - Fixed -Wold-style-cast warnings in netlist code. - Added iterators to pstring. - Moved two macros, added more RAII and improved exceptions. Fixed some bugs in parser code. - Fixed a number of bugs in parser code and exception handling. [Couriersud]
