I think that all the code that does some analysis itself and computes
layers or geometries or whatever, that should be in C++ if possible,
and then accesed from Processing. No need to start porting stuff if
there is not a real need in terms of performance or reusability, but I
think that everything that is not the framework itself can be taken to
C++ and the design would be cleaner
