- access to Sizing object in Circuit object (method getSizing())
- now driver is deterministic since it sorts names in alphabetical order (cannot use name's id since names are destroyed when converted to hurricane and then recreated before drive but with totaly unknow/uncontroled ids)
- OpenChamsException to cleanly throw errors (and not cerr -_-)
- New Schematic object to parse&drive schematic section in xml file
- Lots of checks on node properties
CHANGES:
- directly returns reference on objects' maps/vectors to skim through them (instead of begin/end iterators)
