Improvement of dependency control.

Better handling of stop messages.

Introduction of dynamic scaling.

Also: try to do a better handling of stop signals.

Fix issue when no output-queues were generated.

Introduction of some helper to avoid direct interaction.

Indeed, before this patch, one had to interact with the input queues
directly to fetch their size.

Better handling of misleading input format.

Indeed, before this patch, if one was working directly with the
input_queue without our very own interface, a TypeError may
have been raised.

Introduction of the new project.

This project is an effort to extract core pieces of the PyFunceble
project into some reusable extensions that others can use - too.
