Make Helix Shape in occQt

PCurve is a powerful modeling method, to make helix shapes in occQt to help you understand pcurve better, then you can also can model some intereting shape based on pcurve.

OpenCASCADE does not provide helix curve directly, but you can build a helix curve by the pcurve of a surface(curve on surface). When you understand the pcurve of a surface, you can make a helix curve easily.
