Exercise 03 - Interpreter

Goals

Interpret state machines by using an interpreter. The machine should toggle between the inactive and active states:

• In the inactive state, when a mousedown event happens, go to active.
• In the active state, when a mouseup event happens, go to inactive.

Tips

• Use the same machine as Exercise 02.
• Use interpret(...) to create a service that interprets the machine.
• Start the service with service.start().
• Use service.send(...) to send events to the running service.

Extra Credit

• Send the raw event from the event handler to the service instead. Notice how it fits the event object shape!
• Practice stopping the service when you no longer need it with service.stop() (e.g., after 10 seconds or so).
