1. More optimized selection of prediction schemes for different compression levels on the encoder side. 2. Improved robustness to tampered input data (.drc) 3. Added support for strognly typed vectors of bools 4. Support for logging and squared lenght to our VectorND class 5. Added support for partially defined indices in .OBJ files 6. Added support for loading of normal vectors in .PLY files
