Using aftersim with local files on your PC/laptop
You don't need to set up any external file servers or upload outputs to subversion to use aftersim: you can explore the files stored on your own laptop right away.
This is great for debugging runs and for files that you cannot make public (or that you don't want to make public just yet).
All you need to do is run the Mini File Server program on your local machine, in the folder that you want aftersim to have access to. It is a simple HTTP web server that lets your browser access that folder (and only that folder) via localhost:8000. Your machine's default firewall will prevent any outside network or internet access.
Here's how to set it up.
