Adding rest handler demo

[th31nitiate]

This should add a simple demo of the rest handler. It bear bones as I understand we do not have any specific convention here. Though feel free to let me know if there is anyway I can amend it.

I could of added something like a list that gets modified each time by put or delete. Though I just don't quite have my head around managing states between connections of different type. The rest example for the most part is stateless due to their not being an API token associated with request.

There is likely other methods through default request headers but I felt the need to not over complicate things here.

I was concerned about not having redirects though I realized the API should be accessible by a HTTP client. The curl with the response being returned to the application.

Any tips or advice on how to improve this & make it more compatible would be more than welcome.
