Takes the output of Doxygen XML and parses it to retrieve metadata about the classes and methods.

To create the Doxygen XML files, from the wxWidgets/docs/doxygen directory, do:

./regen.sh xml

To see the results from parsing a particular class, do:

python doxymlparser.py --report out/xml/classwx_<whatever>.xml
