error_occurred event Leave feedback

Occurs when an error occurs in one of the nodes of the search network.

node_event_hub.error_occurred += handler    # subscribe handler(sender, args)
node_event_hub.error_occurred -= handler    # remove the last subscription of handler
node_event_hub.error_occurred.clear()       # remove every handler added from Python

The handler runs on the thread that raises the event, which can be an engine worker thread. An exception it raises there is printed to stderr and ignored; on the calling thread it reaches the engine, as in .NET.
