Port inheritance with deeply nested modules

[DivadNojnarg]

What I noticed:

• If a parent module has 1 child, all its input ports are copied (by default) to the child input ports (unless we specify inherit = FALSE during the nested module initialisation). This is what we expect
• Now we create a nested module in the child module. In the meantime, we decide to add a new input port to the child module. Then the nested module (grand child) will only inherit from the direct parent and not from the grand parent + the parent

There are a lot of use case where it would be convenient to inherit from multiple layers.

This feature should be included with the ability to choose whether to inherit from the direct parent, the whole chain or maybe a given number of parents (if n is 2, we inherit from the parent and the grand parent)...

Do you have comments @xni7 and @m-l-1 ?

I also might have missed something

I like @DivadNojnarg 's proposal. I think the default may be recursive inheritance.
