ES6 module needs exporting

Description

ES6 module needs exporting to allow testing.

Steps to reproduce

The actual vs expected behaviour

At the moment functions are out of scope and unaccessable i believe this is due to the import statement for guage.js.

Yes! This was the issue. I managed to sort of hot-fix it by appending var to necessary functions to force them into a global scope but obviously not the best shot. Thank you for finding this I was wondering what was causing it!

Might work having it all in a class then define the class as a variable on a global scope. Then export class.blah instead of varing it all?

We had a shot at ES6'ing the gauge code, but the issue is that importing it then to a ES5 codebase (new_mapping.js) gave us lots of problems. How necessary are the tests to the gauge?
