Yes, but not in the way one might expect.
Instead of reporting ESIS events as soon as they come in from
the parser, Cost always builds an in-memory tree first; the user
can later regenerate event streams from selected subtrees.
I had originally planned to add a scheme where
event handlers could be interposed between the parser
and the tree builder, but since the in-memory representation
ended up being much more efficient than I had originally
anticipated and since a purely event-driven processing
model is so rarely useful, I never bothered to implement it.
