FEATURES
./Features on first sight
• Clean client API (ideally you shouldn't be using anything else)
• Simplified DB schema
• runtime vs historical data separation!
• eg process instance is in DB only during execution, afterwards it is
deleted and stored in a history table
• Performance boost (and no method-chaining)
• Fancy web console (GWT)
