function BatchExampleForm::generateBatch2

Generate Batch 2.

Batch 2 will process five items at a time.

This creates an operations array defining what batch 2 should do, including what it should do when it's finished. In this case, each operation is the same and by chance even has the same $nid to operate on, but we could have a mix of different types of operations in the operations array.
