1. TriaixalStressController: originally compilation fix, but Luc was faster; Bruno, I tried to replace on c-array with boost::array; if that works, you could use it for other c-arrays as well
2. Add yield surface query function from python to Law2_..._Cpm
3. Make plot support label translation via yade.plot.labels
4. make chunkSize very small for debian; add strip for the optimized build
