When creating material from python, one can choose what type of material to create (HomogeneousMaterial or MaterialBySLD). This functionality should be available from GUI. For example, user should have ability to choose material type of particles, layers, etc. It is also necessary to make sure, that all material types are compatible in constructed sample and throw some warning to user otherwise.
