Beginner question: @import syntax doesn't work with skpm
I see lots of plugins using `@import` 

I was following the sketch plugin tutorials but now I'm trying to use this specifically, https://github.com/matt-curtis/MochaJSDelegate 

from this tutorial https://blog.prototypr.io/how-to-create-floating-sketch-plugins-part-ii-626de632996b

```
@import 'MochaJSDelegate.js'
```
I can't seem to import it correctly. Any help would be greatly appreciated!!
