Provide example of using the stand-alone mode

[originalfoo]

I read the docs here: https://github.com/atom-minimap/minimap/blob/master/docs/Developers%20Documentation.md#stand-alone-mode

But it seems the stand-alone mode still requires some sort of infrastructure that I'm not familiar with.

Would it be possible to create a simple demo showing how to use it - for example, a basic web page with a string array passed in to the minimap, ideally with some tokenisation for colours?
