Fix 1004 - add function body upon call to add_fct

[ilyaZar]

Per commit message:

• fix ASadev, I want the body of a function when I call add_fct #1004 adding bare skeleton function body
• function name taken from 'name' arg to add_fct

So add_module(fct = "fct_name") creates a file "fct_name" without pulling above template. This could be fixed, though I am not sure what the exact behavior should be. #1004 explicitly asks for changing add_fct() not add_module().

The body is a matter of taste, I am happy to change it :)

Thanks a lot @ilyaZar!

For the body, my general philosophy is: "if you have to remove something every time, you probably need to prevent it from being added in the first place" :) So yeah I would prefer an empty body & params if that's ok with you to make the change ?

That makes sense!
