doc_tex and actual code (regarding function parameters).
before comparing declaration-strings, they are normalized:
* variable names and default values are eliminated
* spaces are compressed/removed
* function argument types can be (nested) template parameters,
pointers and arrays (not mixed with "(" and ")", however)
read in xml files from our tools and from doxygen and list
some interesting features (classes, functions, their locations in c++ code,
their current documentation etc)
