Activity and collections
We now have a collection of agents - bugs
Schedule now takes as target the collection object - a List instance
The collection object passes on the message to each bug
modelActions = [ActionGroup create: self];
[modelActions createActionForEach: bugList message: M(step)];
[modelActions createActionTo: reportBug message: M(report)];
modelSchedule = [Schedule createBegin: self];
[modelSchedule setRepeatInterval: 1];
modelSchedule = [modelSchedule createEnd];
[modelSchedule at: 0 createAction: modelActions];
