to create a persistent bat

+
+#In the second run, comment initBatCreate call above and uncomment testrun
call below to invoke it. Cardinality count will be different for different runs.
+#In the third run keeping the initBatCreate commented, and testrun
uncommented, also uncomment the bat.setTransient in the initialize function to
get correct cardinality count.
