There are regular comments about wasStartedByActivity.

MacTed was saying why don't we also have wasStartedByAgent.

Someone else  was saying, why don't we have wasEndedByActivity? ... and ByAgent.

In the spirit of simplification, we could drop the concept.
Whenever we want to write

wasStartedByActivity(a2,a2)

we would instead have to write

wasStartedBy(a2,e)
wasGeneratedBy(e,a1)

for some entity.  


Thoughts?
