[Insight-developers] Doxygen Updates

[Bill Hoffman]

I have done four things to the doxygen process in ITK:

1. I have created a perl script to pre-process the .h files and
create groups for methods that share a single doxygen comment.

2. I have incorporated the vxl doxygen perl script, so now there are doxygen comments
for the vnl library.

3. I have install tex/latex/ghostscript on public, so now the inline
formula stuff is working.

4. Moved the doxygen config file to Utilities/Doxygen along with all the
perl scripts.
