%Docstring
Creates a circular string with a single arc representing
the curve from ``p1`` to ``p2`` with the specified ``center``.

If ``useShortestArc`` is true, then the arc returned will be that corresponding
to the shorter arc from ``p1`` to ``p2``. If it is false, the longer arc from ``p1``
to ``p2`` will be used (i.e. winding the other way around the circle).
