/*
- get rid of STL
- NpArticulationLinkArray with more than 4 entries
- big convexes Xbox => PC
- put a cache in "convertClass" function
- remove MD one at a time and check what happens in the converter. Make it robust/report errors
- for xbox, compare against source xbox file if it exists
- maybe put some info in the header to display "File generated by ConvX 1.xx" on screen (to debug)
- report inconsistent naming convention in each class!!!!
- try to automatically discover padding bytes? use "0xcd" pattern?
* do last param of XXXX_ITEMS macro automatically
- what if source files are 64bits? can we safely convert a 64bit ptr to 32bit?
