Asset: Pimp my Editor - Javascript Help

Bought the Asset "Pimp my Editor" to help organise my Inspector.

If I was using C# then it's ok because there is a tutorial however for javascript the only instruction is:

type:

@Group("GroupName")

And that's it! supposedly I'm done. The problem is that nothing happens.

I have a feeling that I'm supposed to include something at the start of my script that links it to the PimpedMonoBehaviour however there is no example in Javascript to show how to do that.

Moving the program into standard assets produces a file not found error. Creating a class and extending to PimpedMonoBehaviour results in an error where PimpedMonoBehaviour cannot be found.

I bought the program because it is supposed to make the process easy however it's only provided more questions...

Any help would be greatly appreciated. I did write to the creator of the software however I have no idea how long it will take him to reply.

All I want to do is either make a title in the inspector OR preferably make a title/heading that I can click on to expand variables in that group.

Any help will be extremely appreciated. Thankyou.
