[Doxygen-develop] PATCH: Exclude C++ std::string/wstring from diagrams

[Fredrik O. <for...@gm...>]

The BUILTIN_STL_SUPPORT option is great for enabling doxygen to parse
C++ classes containing STL containers and smart-pointers. It does,
however, also lead to some "noise" in the diagrams; especially for
text strings. I don't personally see the big value of adding separate
boxes for e.g. std::string members in collaboration diagrams for
classes containing strings. Instead, text strings could be considered
a "primitive" type, like int, float etc.


Would it be possible to consider the STL string classes as "primitive"
types, and exclude them from collaboration (and possibly other)
diagrams?


A patch that attempts to do so is attached.
