The option structure defines options applicable to creating a curve from
a set of edges.

'curve_dir'     : structure to explicitly set the curve direction. If
                  the direction is not set, the direction of the resulting
                  curve will have a tangent that is in the same direction as
                  the first edge in the supplied set
