  + Redis -> will be used for any non-local deployments
  + InMemory -> a VERY BASIC implementation that is used for local execution
- events package
  + GenericReporter -> responsible for reporting events, can be used to send any type of event and payload
  + GenericReader -> responsible for reading events from a stream, can be used to register handlers for any type of event and payload
  + ReaderFactory -> responsible for launching readers for any type of consumer group&name.
- webhook package
  + The wire frame of the webhook package.
- gitrpc/events package
