Fix import errors when loading multiple matchers (fixes #60)#62
Conversation
Multiple third-party repos share generic package names like `src`. Python caches the first import in `sys.modules`, so loading a second matcher silently gets the wrong module. `add_to_path()` now scans the added directory for packages that are already cached from a different third-party directory, and flushes the stale entries. User code and pip packages are never affected.
