adding java files for KafkaSpout directly to facilitate debugging. Added a pauseUntil (commented out)
which helps the program continue running so that we can crawl around and look at stuff in debugger.
(if we stop in the debugger, then the inprocess zookeeper is suspended, so we can't poke around).
See pom.xml entry ->
<!--  Including src jars for kafka spout for debugging. can remove these if we enable the dependency below -->
also Changed number of spouts and partitions to 1 so things are easier to debug.
test pass with sequence changed so that we start up topology first, then after that we feed the kafka topic.   This seems to work.. we pick up the messages as expected
