/*  Test_task
 *
 *  This task is used for three test tasks.  It obtains its task id and
 *  based upon that id, performs certain actions.
 *
 *       Task_1 delays 5 seconds and deletes itself.
 *       Task_2 delays 10 seconds and then loops until
 *             deleted by the third task.
 *       Task 3 delays 15 seconds, then deletes task 2 and itself.
 *
 *  Input parameters:
 *    argument - task argument
