[Vv] Format for deformation fields in VV

[Simon Rit]

Hi Bilal,
All the ITK formats should be accepted so if .nii.gz is readable ITK,
it is readable by VV. It's not because the format is not listed from
the gui that it cannot be read. Just give it a try from the command
line, e.g., vv image.mha --vf vf.nii.gz
The format is one file with the displacement vector at each point,
i.e., itk::Image< itk::Vector<float, 3>, 3>. The vector is in mm and
the location of the vector is given with the origin and spacing of the
image, as usual in ITK.
