[vtkusers] VTK-DICOM v0.3.4

[David Gobbi]

I've made a new release of my vtk-dicom package, the source code
is available here:
https://github.com/dgobbi/vtk-dicom/releases

Doxygen documentation and pdf document:

The main addition is that this version support the VTK java wrappers,
so that you can use the DICOM reader and writer classes through
either C++, Java, or Python.

The features that I'm working on for future releases are as follows:
- private dictionaries
- writing more image types (right now the writer supports CT,
  MRI, and secondary capture).
