# Improvements/ToDo
#
#  - actually call doxygen to make the xml
#    - for directories, additional INCLUDE, etc. with GUI
#    - delete temporary files or better make doxgen output them on stdout? 
#    - have a way in the plug-in interface to import multiple files at once?
#    - another way could be to let doxygen put everything in one file?
#
# - for single class import connect by searching base classes in the diagram
#
# - some layout algorithm based on inheritance
#   - maybe this should be done as an extra script/plug-in becasue it could be 
#     useful on already existing diagrams as well
#   - some smart way to handle size change with 'visible comments', maybe
#     also tweaking wtih wrap-after-char
#
