There isn't anything specifically that will close a curve, but you can test and see if a curve is closed, split the list based on whether its closed or not, create a line segment from the end points, join the previously open curves and connecting lines, and merge the two streams back together. The only thing about this is that the curves that were open are now at the end of the list. That may not matter, but if you were depending on that order being there, you may have to resort the curves after they're all closed.
