Sounds like a good idea. We now generate Python script that loads the
Function (or Mesh) from file and then calls Viper from Python.

Does Viper support direct plotting of .vtu files? In that case, we
would not need to call Python from C++. We could generate a .vtu file
and then call Viper with that file (using system()).

I don't have time to fix this now, so either find someone to fix it or
put it on the TODO list.
