Subprocess must be started by the none event

A subprocess is started by a call from the upper-level subprocess or process: “now proceed to work, it's your turn”. Therefore a subprocess should not begin with an exeternal start event like timer or message. (Exeternal start event is a qualified property of a process.)

• Make process start and end explicit
