Default Closure Zone Template System

Currently if you pull out to create a Closure Zone from a Node Group, it's not very clear about what you are supposed to do for the function. There's no any nodes, there's also no minimum linkages posted. Even worse, currently the Closure Zone bypassing mechanism only allows for sockets with the same name. such as "Value" in and out. so the linkage can bypass without an actual closure zone. Otherwise, in this case, as "Value" and "Output" are different socket name. values will not be passed, and this group output is 0.

At the end, I hope when you pull out closure, it can already form a template to have a basic complicate function. So it can be faster for users to get hands on about the context, what this closure zone expects and how to use it, without specifically going through the manual. Having a template system in such a case can also save some time to speed up the workflow while keep flexibility of closure system.
