Docker x-forwarding experiment
# X-Forwarding experiment to run graphical applications inside Docker without host UID specific image/container
Usage:
```bash
# Builds "xforward" docker image
./run.sh
# Then from inside the running container
xclock
```
Note: Linux only. This used to work on mac, but potentially the Mojave upgrade has broken it.
