Performance issue on large project

[kriomant]

I tried to use clang-expand (via Atom) on our company project, which is Chromium-base and thus is pretty large. As far as I understand, tool searches all C++ files using provided glob and parses them all, which isn't an option when there are thousands of them. Even just listing them all takes enormous amount of time.

What I propose is to require rule telling how to find implementation file corresponding to header. clang-expand may then search for functions declaration in headers, use rule to find corresponding source file and parse only it.
