The below will setup automatic WiFi configuration via text file. The way this will work is you plug in a USB disk with a file named ```wifi.txt``` with the ```essid``` as the first line and ```password``` as the second line in the file. On boot a small script will run that reads the file and re-configures the PiFrame's WiFi to use the new values.
Can be used for setup and/or re-configuring WiFi if something changes.
