[vtkusers] Problem of vtkPointWidget test

[Florian Bruckner]

ok, this is simple. you don't even have to define a picker, because
your pointWidget is by default "pickable". And you also have already
defined an observer for the interactionEvent. Just adding
print obj.GetPosition() to the ProbeData(obj, event) function prints
the current position of the widget every time it is moved.
