 manager = HelixManagerFactory.getManagerForROLE(); ROLE can be participant, spectator or a controller

 manager.connect();
 manager.addSOMEListener();
 After connect the subsequent interactions will be via listener onChange callbacks
 There will be 3 scenarios for onChange callback, which can be determined using NotificationContext.type
 INIT -> will be invoked the first time the listener is added
 CALLBACK -> will be invoked due to datachange in the property value
 FINALIZE -> will be invoked when listener is removed or session expires
 
 manager.disconnect()
