Save a 3-D vector field of components X, Y, Z to the file filename in VTK format.
This file format is used by Mayavi2 or ParaView for example. X, Y and Z should be 3-D arrays of the same size, each storing vector components in a given Cartesian direction.
If no write errors occurred, output argument status is set to 1, otherwise 0.
