Added preliminary getVolume() and getSurfaceArea() implementation to all Shapes.

  • only BaseShapes are truely usable, the rest is mostly marked as TODO.
  • the problem is that intersections are not so easy to handle. Probably, we have to use polygonal intersections there and approximate volume calculations.
  • the functions return -1 when not implemented yet. this is preparatory to start approximate calculations at the top node of the Shape "graph" if -1. is returned from the implementation.
  • Property mode set to 100644
