[Swarm-Support] passing information between classes

[Derek Farren]

Hello everybody.

I have a doubt about passing information between classes. It ends on a
specific question: Whats the diference between creating an instance of the
class "ClassA" via id aClassA and ClassA * aClassA ?

Sometimes both ways work, but some other (when the imported class is
ModelSwarm) just the first choice works.

Thanks, Derek
