Correct, the MARK_CUT_START and MARK_CUT_END do not really have anything 
to do with the commercial flagger, strictly speaking..   a 
CommDetectorBase implementation just needs to provide a map of 
MARK_COMM_START and MARK_COMM_END's, and what the rest of myth does with 
that is none of its concern.

Glad you got it sorted out,
