Add "Module docstring"

[federicovallucci]

Describe the feature request Is there a way to use this extension also to generate the module doc string? I know very popular one like google or numpy are already templates you have for making the docstring of a given function.

What about having those templates also for the each module (file)? Thanks

More specifically, it indents the module docstring upon generation
