        End construction, and attempt to build a closed wire.

        :return: a CQ object with a completed wire on the stack, if possible.

        After 2D (or 3D) drafting with methods such as lineTo, threePointArc,
        tangentArcPoint and polyline, it is necessary to convert the edges
        produced by these into one or more wires.

        When a set of edges is closed, CadQuery assumes it is safe to build
        the group of edges into a wire. This example builds a simple triangular
        prism::

            s = Workplane().lineTo(1, 0).lineTo(1, 1).close().extrude(0.2)
