Is any option to make a Mean Curve?

something like this (the mean line):

TweenCurve is the obvious command to use - but the results depend on how the curves are parameterized.

A method for finding the mean curve which is the set of points which are equal distant from the two side curves:

- Create set of circles which are tangent to both side curves. (Spacing of circles is not critical.)
- Find center point of each circle
- CurveThroughPt through center points. (Chord may give smoother result than Uniform.) Alternative would be InterpCrv.
