[kepler-dev] creating a compositeActor and saving it in the library

[Chad Berkley]

The procedure is the same as for normal actors, except that the actor 
metadata is a bit different.  For an example look in 
src/actors/CompositeActor.  The main difference is that the class 
defined in the entity is org.kepler.moml.CompositeClassEntity instead of 
ComponentEntity.  You still have to add the other kepler attributes 
(i.e. entityId, class, semanticType, etc).

If you want another example, create a composite actor on the canvas by 
dragging TypedCompositeActor from the tree, then put some actors in it, 
the right click on the composite and select 'add to library'.  that will 
save it as a kar of which you can then look at the contents.
