8/17/2012 V1.6.0 Fix a error occurredin Maya 2013. A new parameter has been added: clockwise. It allows your spiral curve swirl in different directions. (Thanks Joel Goodman's advice) 1/19/2012 V1.5.0 Now it is in Python version. So it's doesn't care which version of Maya you are using (newer than 8.5) 9/30/2011 V1.1.0 Added a attribute --- startAngle to the node. now you can rotate your spiral curve along the profile curve.
