 Restart scenario
 ----------------
   Restart methods handle the scenario when participant shut down and restart.
+  During RESTARTING, compositions and instances will be stored in participant memory with In/Out Properties, 'useState' and 'operationalState'.
   The method handleRestartComposition will be called for each composition and will be present the 'state' at the time the participant shut down.
   The method handleRestartInstance will be called for each instance element and will be present the 'deployState' and the 'lockState' at the time the participant shut down.
