change resource on worker to be configurable
Merge pull request #67 from manuzhang/add_kafka_conf_file

Add kafka conf file
add dependency of examples into core/build.sbt until we resolve #30
update README.md to document that you need to run 'sbt clean publishLocal pack'
Remove circular dependency but add hardcoded reference to examples lib for local, master, worker. Temporary workaround until we can pass the jar (or jar path) to the master and have it loaded dynamically
