You are specifying that function to be called to start the worker yourself.
In your module group_supervisor.erl you provide a child_spec() in the return
value of init/1:

  {mucfsm, {sim_group_fsm, start_link, [Opts]}, transient, 60, worker, [sim_group]}

The form of which is:

   {Id, StartFunc, Restart, Shutdown, Type, Modules}

The second argument, StartFunc, has the form:

   {Module, Function, Arguments}

You provided:

	{sim_group_fsm, start_link, [Opts]}
