- added transforms to put all object transforms in a single place
- added Wavefront .obj file parser
- removed frame buffer's abstract class
- improved vectors, matrices, triangles, vertices and vertices data by putting all code in header file
- added vector's operations
- changed from NULL to nullptr
- miscellaneous improvements
