TVB-2728: Fixed ICA Analyzer
Created by: VinczeRobert
I just went along the lines and fixed the shaped of the matrixes where they didn't match or they couldn't be multiplied.
Now it works when you leave the components field empty and it works if you choose a value for it as well. Tests also works.
I left the WIP because I still need to compare it to 1.5.6.
