SlicerLiver extension layout

[RafaelPalomar]

@ALive-research/alive-software, I have created a post about the layout of the extension on discourse; I would like to know the opinion of the Slicer devs. We need to decide (I believe) between:

• Single hybrid module containing a .py module file and C++ components distributed in different folders.
• A set of qt-loadable-modules providing the core components + a qt-scritped-module connecting all the components.

We have to keep in mind that, whatever the case, a .py file as entry point for researchers is desirable.

Let me know what's your opinion on this.
