Fixes #30 - Makes transactions optional
Fixes #25 by locking producer access around a read/write lock, as when using a transactional producer, it's not actually completely thread safe.
Fixes #26 Document config options better - maxConcurrency, numberOfThreads, maxUncommittedMessagesToHandlePerPartition documentation
Fixed #12 Create a parallel consumer which doesn't require a Producer instance enhancement
