Tutorials are organised in 3 levels (Basic, Intermediate and Advanced).
Each tutorial is contained in a separate package containing a README.md file that describes the tutorial and how to run it.
The org.jeasy.batch.tutorials.common package contains classes that are common to all tutorials.
All examples use tweets data. Tweets are represented by the org.jeasy.batch.tutorials.common.Tweet bean.
