Provide typing

[tmoulignier]

Hello,

Is it possible to provide typing in classes properties and functions? for example:

def get( idstr): becomes:

from .registry.ig import ig
def get( idstr:str ) -> ig:

That way, people using IDE can crawl from a function to another, and have auto-completion working.

The documentation also does not display properly in markdown (in VScode at least) as we would require two line break (or add an \n at the end of the line).

Thanks
