Update cacheFactory.js - #6068

https://gist.github.com/caitp/f289cecaa6983a663c64 I've edited this to look a bit more complete (because the demo gets rendered underneath it the source).

So, I'm a bit iffy about merging this immediately, because we're migrating the doc generation stuff over, and there's a bug in the current doc gen stuff which hides the closing </script> tag, making it a poor example.

Once that stuff is pulled in I'll merge if it looks okay.

Also, don't worry about closing and re-opening the pull request, it's fine :)

Sounds good. Thank you!

@caitp what do you think about this now?

I think maybe using the live example format is not the best choice, because the example window is really big (bigger than it needs to be), and it's not showing anything very helpful. Maybe it would be good to fix this once there's a way to have more control over it.

I think I'm going to convert this to GFM-style example and merge it, it looks okay to me
