/* **level\_data** is created and populated with

* initialization, such as the timeline.
* A timeline allows creating a sequence of events
* on a, well.. time line. Each event has a start time,
* duration and callback function the will get called
* each time the timeline is updated and if the event
* is active.
* We use a timeline to animate the title, creating 3
* events: (1) slide the title into the screen (2)
* make the title "bling" and (3) slide the title out
* of the screen.
* Using the SECOND and SECONDS constant is for
* the sake of readability only.
