TVB-2694 Integer input validation + part TVB-2728 ICA Fix
Created by: VinczeRobert
For the integer input validation I made the exact same thing as with floats. I saw there a TODO saying that we should raise an exception but I don't know what kind of exception so I just left it like that.
For ICA, I don't really know what those parameters mean, but based on their shapes, I deduced how they should be rearranged so the analyzer doesn't fail at launching. It works now, and the visualizer works as well.
