Installation -
This javascript (code.js) is meant to be put straight into your personal vector.js file.
Operation -
The script checks every 30 seconds to see if the page that you are currently reading has been changed. If so, a small icon will appear at the bottom left of your screen alerting you to the revision. When clicked, the changes will be inserted into the page and will be highlighted.
