add: compose, readme, and dockerfile for qt gui

@@ -3,12 +3,24 @@
 The following docker files are split up for the queue-server and http-server for testing. The docker compose here will spin them up together along with a networked redis server. They are bare bones and will lack the full functionality of a collection profile, but should be useful for simple testing.
 
 ## To run the containers:
+On a Mac, to use the display you will need to install XQuartz and allow connections from network clients.
+The queue-monitor gui image is built on [jozo/pyqt5](https://hub.docker.com/r/jozo/pyqt5). 
+
 ```bash
 cd docker/queue-server
 docker build -t qserver:latest .
 # The http-server image is based on the queue-server image so goes second.
 cd ../http-server
 docker build -t http-server:latest .
+cd ../queue-monitor
+docker build -t queue-monitor:latest .
 cd ../
+export LOCAL_DISPLAY_IP=$(ifconfig en0 | grep inet | awk '$1=="inet" {print $2}')
+xhost +
 docker-compose up
 ```
+
+#### If using a Linux Machine, replace the `LOCAL_DISPLAY_IP` used for display:
+```bash
+export LOCAL_DISPLAY_IP=$DISPLAY
+```
