A listener used to monitor when a TestNG run starts and ends. When implementation of this
listener is wired into TestNG, TestNG will ensure that

  
onExecutionStart() gets invoked before TestNG proceeds with invoking any other listener. 
onExecutionFinish() gets invoked at the very last (after report generation phase), before TestNG exits the JVM.
