completed by: Agustin Zubiaga
mentors: Walter Bender, Gonzalo Odiard
There is a lot of redundant code in Sugar activities that use collaboration. Much of this code could be consolidated into an extension to the Sugar activity class.
Task:
(1) Add an extension to the Sugar activity class to fold in the general case for collaboration.
(2) Modify an existing activity to demonstrate the use of this extension.
