%%% Common Test Framework Event Handler
%%%
%%% This module implements an event handler that CT uses to
%%% handle status and progress notifications during test runs.
%%% The notifications are handled locally (per node) and passed
%%% on to ct_master when CT runs in distributed mode. This
%%% module may be used as a template for other event handlers
%%% that can be plugged in to handle local logging and reporting.
