track objects in Physics

[walter]

In discussion with some teachers last week, we thought it could be very useful to be able to expose data regarding position and time of selected objects in a Physics (box2d) model. Either capture these data for display in another program, such as Simple Graph or Turtle Art, or allow them to be displayed, perhaps in a secondary toolbar. Especially in light of the ability to build more precision constructions with tools like Turtle Art, there is an opportunity to engage in more sophisticated modelling and simulation, which would be greatly enhanced if Physics would "show me the data".

Have not yet looked at the code to determine where we would need to intervene.

Thanks for the feature request. I've been looking in to landing some past patch efforts that allow objects to trace paths onto the canvas, this feature request seems like a natural extension to that future feature. I'll keep it in mind when I work on the re-design!
