Following Updates are done

• Now JWT OAuth 2.0 is supported.
• Now we can document response types for the API. See the jwttest.json for details.

Attached the response documentation screenshot

This is an IDE specific addition. It should go in your personal/global .gitignore

Aah, yes,, true... sorry for that. Will take care of this in future.

what exactly does this do?

@kushal-likhi this is a nice feature to add. I'd like to clean up this PR so we can merge it. I just have a few concerns.

1. I don't know why the domain module is needed
2. white space is changed everywhere so it's hard to see what the actual changes are, this should be cleaned up
3. private api's should not be committed to the core application, we need to support loading external api definitions in a better way.
4. since I have no familiarity with JWT it will take a little research to verify the feature

aside from the nitpicking this looks like a great addition to iodocs :)

I'd like to add JWT authentication to my docs. Anyone have any luck with this?
