* Description: 
* This step performs operations that generate notifications
* It sends messages to the concurrently running listner step / thread
* informing it what notifications it should be listening for, when it
* should be listening when it should stop listening, also it waits for
* messages from all the listeners infroming it that all mesasges have
* been received.
* Sending Messages:
* Set shared string to contain the number of notifications to expect. (10)
* Append shared string with valued of event in notification. KSharedEvents (1 2 3 4)
* Append shared string with value of contact id in notification. KSharedContact. (1 2 3 4)
* KSharedContact and KSharedEvents are synchronized so that at index X lies the contact and
* event value for notification X+1.
* Append shared string (KSharedNextTest) with single character. Signifies new
* test case has started. (AAAA)
* Receiving messages:
* Read shared string length signifying the number of listner threads
* that have finished from this test case. If this number equals number of
* listener threads, stop this test case and start next test case. (AAAAAA)
*
