quickEccentricity Method

Return a quick estimate of the eccentricity of the ellipse.

• The estimator is the cross magnitude of the product of vectors U and V, divided by square of the larger magnitude
• for typical Arc3d with perpendicular UV, this is exactly the small axis divided by large.
• note that the eccentricity is AT MOST ONE.
