Libclang. Cross-referencing translation units with Unified Symbol Resolution USR.

Hello,

I have spent the last months in developing a documentation tool based on lib clang & its python bindings, which can generate activity diagrams from annotated C++ code. It works for a single translation unit, which in my case is a single .cpp source file (e.g., ‘main.cpp’). Now I would like to make this tool work properly for a code consisting of several source files.
