Simple implementation of executing the step as a call to a ITasklet, possibly repeated, and each call surrounded by a transaction. The structure is therefore that of a loop with transaction boundary inside the loop. The loop is controlled by the step operations (StepOperations=RepeatOperations)). Clients can use interceptors in the step operations to intercept or listen to the iteration on a step-wide basis, for instance to get a callback when the step is complete. Those that want callbacks at the level of an individual tasks, can specify interceptors for the chunk operations.
