This Vim plugin will help switching between companion files (e.g. ".h" and ".cpp" files)

**Enhancement in this fork**

This fork adds intelligent directory discovery to handle more complex project structures that the original plugin couldn't handle.

The plugin now automatically detects companion files in:

**Scoped headers:**
```
src/file.cpp ↔ src/myproject/file.hpp
src/file.cpp ↔ src/namespace/file.hpp
```

**Nested structures:**
```
project/src/file.cpp ↔ project/src/include/file.hpp
project/src/module/file.cpp ↔ project/src/module/public/file.hpp
```

No configuration required - it works automatically as a fallback when standard patterns fail.
