Minor mistake fix: in DKappa, i was set to 1 in function body.
Checked calcWfMA_ik for f=4,5. Everything fixed and equal to Mathematica
expression.

- f=5 was correct.
- f=4 had an lower-level structure bug.
Fix calcW2MA_ik.

- Some brackets were missing and thus, whole structure changed.
Fix calcW0MA_ik.

- Found some small issues like "*" instead of "+" and "d1" instead of "d2".
- A little bit reformatting.
