Porting Assets into Runtime Editor (help needed)

I'm planning to use a Runtime Editor asset on the Unity Asset Store. And I am amazed.


First question:

1. How do you achieve such editor accessibility in the Runtime
2. How would I port Unity Editor assets such as Playmaker into the Runtime

I imagine I would have to recreate the UI Elements the assets engage with, but I just need a definitive guide, reference to an API, just anything that can help. I've already emailed the creator and am awaiting a response.
