Morning fellow mappers,

I’ve just uploaded my script to my repository 
<https://github.com/SirTypesALot/OSMPhoneNumberFormatter>, do note that I’ve 
removed the section of the code responsible for uploading modified data back to 
OSM, I will put the code back when the script is ready to be deployed.

Regards,
Marc
