How to create a parabola?

[ThibautBaissac]

This is a great project!!

I am able to revolve a lines around an axis:

profile = IGES.IGESGeomLine(IGESPoint(0,0,0),IGESPoint(100,0,0))
centerline = IGES.IGESGeomLine(IGESPoint(0,0,0),IGESPoint(0,0,1))
revolve = IGES.IGESRevolve(profile,centerline,0,2*np.pi)

Now, I'm trying to create a parabola surface (using the revolve function again).
I have the parabola parameters but I'm not sure how to use:
IGES.IGESSplineCurve()
What are the breakpoints and 12 polynomial parameters?

Thank you very much for any help :)
