The tracker

- To display the value of the time-series at a certain instant of time.
- To trigger the plugins in the category "StatePublisher".
The tracker can be enabled and disabled using the button "A" (bottom left
or the central area).
It can be moved either:
- moving the slidebar at the bottom ("B") or
- pressing SHIFT+Left-Mouse on
the a specific position of the plot.
