Notes

This exists mostly to facilitate development workflow. In time it could be augmented to support fancier features such as wildcards, file lists, mixed file types, and the like. Note that the filter string is hard coded here; its details might depend on the intrincacies of the registries, loaders, and data classes. In other words, this is brittle code.

run()

Start thread to read the file.
