/**
 
This script adds a phone icon before every phone number found. Click to dial via your local soft phone (what
happens is the same as clicking on a tel: link), right click to copy the phone number to the clipboard.
 
My motivation for writing this was to have a solution that I can trust because the code is simple enough to read.
