Detailed Description

Clients of various APIs that cause global effects on the DAG can optionally implement this interface.

This allows the clients to handle the various sorts of updates that happen.

A DAGUpdateListener automatically registers itself with DAG when it is constructed, and removes itself when destroyed in RAII fashion.
