It seems API document of `Model` class is missing


#1

I got 404 on http://atom.io/docs/api/v0.61.0/api/classes/Model.html
Is the class private?

Thanks,


#2

I found source code of Model.


What is the purpose of Model class
#3

I understand the code but, I still don’t understand its purpose in a larger context as lots of other classes extend this. I was hoping you could explain it to me, if you have figured it out.
