Model SignalArrow defines an arrow that is dynamically visualized
at the location where its frame_a is attached. The
position vector from the tail to the head of the arrow,
resolved in frame_a, is defined via the signal vector of
the connector r_head (Real r_head):
The tail of the arrow is defined with parameter r_tail with respect to frame_a (vector from the origin of frame_a to the arrow tail).
