%%
%% this module models a typical manager/worker pattern, where manager may spawn a large number of workers
%% required behaviour:
%%
%% 1) manager must log unexpected worker exits
%%
%% - manager must trap exits in init function -> 'process_flag(trap_exit, true)'
%% - workers must be spawned with spawn_link
%% - worker exit messages are handled by manager handle_info handler [where they can be logged etc]
