Loading and saving of 4D polygon models does not work properly
- When saving the project as *.mitk file, those 4D polygon models are not included in the saved project file
- When saving the 4D polygon model, each timestep is saved seperatly in a stl/vtk/vtp file. No possibilty yet to store it in one file.
- A 4D polygon model, which timesteps has been stored in seperate stl/vtk/vtp files, cannot be loaded as a merged 4D model, only as single 3D models.
