Illustrator script to clean export svg icons

/*
This script loops trough the artboard and exports each artboard to svg.
The destination folder depends on the artboard width. 

!!! This script doesn't currently creates the necessary folder so you need to create the folder structure before exporting. 

The destination will be relative to the illustration location: /export/svg/[icon-width]/[artboard name].svg 

Artboards with a name starting with - will not be exported
