Hi Goranka,
     the rank-2 tensor field (the induced current or the induced
magnetic field) is split into 3 cartesian components, and
written into 3 separate files, as vector fields

When I first implemented the routine, I didn't have any fancy
visualization code in mind (like OpenDX, MayaVi, VTK, ...)
and I've implemented instead for Xcrysden. Xcrysden can output
small 'arrows' associated to fake atoms. The problem is that
the visualization becomes extremely slow.

This said, the format is open, and if you have ideas and
suggestions, they are welcome.
