ITKWriter is broken - error about SetFileName

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Load dataset, I used http://pubimage.hcuge.ch:8080/DATA/MAGIX.zip
2. Use vtktoitk to convert
3. Use ITKWriter to save in Analyze format (meep.hdr) (other formats don't 
seem to work either)

What is the expected output? What do you see instead?
Expected file to be saved in the specified format. Instead, an error 
message is shown:

Unable to execute part 0 of module dvm3 (ITKWriter): invalid null reference 
in method 'itkImageFileWriterIF3_SetFileName', argument 2 of type 
'std::string const &'

Introspecting reveals that obj._config.filename is a unicode string, while 
obj._writer.SetFileName only accepts normal strings. 

Changing line 123 of ITKWriter.py to:
self._writer.SetFileName(str(self._config.filename))
fixes the issue.

Using the Analyze file format still doesn't work, however, and displays a 
somewhat 
cryptic error in a vtkOutputWindow: "AnalyzeImageIO (0CDF90F8): ERROR: Analyze 
7.5 
File Format Only Allows RPI, PIR, and RIP Orientation". I'm not sure if this is 
a bug, 
or how this should be solved.

Other formats like .mha work fine with the patch applied.
