[sugar] Adding 'Collaboration' to an activity

Hi Julius,

I don't know if you've already been answered by Reinier, but here it goes

Reinier and I programmed a sharedstate manager while in Cambridge, that
takes care of setting up a tube, and managing shared objects (versioning,
collision, and so on), for generic Python objects. It can be found on git
(/projects/sharedstate), and you can find an example implementation in the
very project folder, and another one in /projects/calculate.

If you're not using some kind of event-based collaboration (which is, for
instance, the type that the memorize activity employs), this might speed up
sharing, as there is almost nothing to programm (just create a sharing
helper, and add the objects to be shared to it).

Mail me if you have any concrete question.
