[Getdp] Solving 3D magnetostatic problem

Well, I rewrote the scripts and now it works. I still don't know
where the problem was. I'll probably add this to the wiki,
because 3D magnetostatic computations are quite useful IMO.
However, now I have another problem: Is it possible to
export the resulting vector field to some format readable
by ParaView (vtk?)? If not, are there some conversion scripts?
What format is the best for writing my own conversion utility?
