API which controls the Timeline, the UI component which allows network exploration over time.

The Timeline API allows to set custom bounds and visible interval. The timeline is the UI component which controls the network exploration over time. It is connected to the `DynamicAPI` which controls the time scale and intervals. The API also allows to control the animation (i.e play feature).

The `TimelineController` is managing models (one per workspace) and is the access door to the system. This controller is a service, and can be retrieved by using the following command:

`TimelineController tc = Lookup.getDefault().lookup(TimelineController.class);`
