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.
