build a new timeline display and attach it to the UI-Bus.

identityused to refer to a corresponding element in the Session
trackIDthe mandatory root track used in the associated Sequence
nexussome established connection to the UI-Bus, will be used to register the embedded TimelineController as communication partner to respond under the given ID.
after creation, the widget can just be hooked up and wired like any ordinary GTK element; it becomes passive and just responds to signals. The active role is played by the controller, which also responds to mutation messages; this is the only way to populate the timeline display. Likewise, a timeline shall be deleted by sending an respective mutation message to its parent element, the one that created it, typically also in response to a message. Non the less it is possible just to delete a TimelineWidget, since it is a Gtk::Widget, and the controller is also sigc::trackable and additionally, as a gui::model::Tangible, it will deregister automatically from the UI-Bus. After that, any further messages towards this element will be dropped silently.
