iFit/sw_ellipse

 creates an array of the 3D coordinates of the ellipse circumference

 points = SW_ELLIPE(r0, n, R, N, {v1, v2})

 Input:

 r0    Center of ellipse, dimensions are [3 1].
 n     Normal vector to the ellipse surface, dimensions are [3 1].
 R     Minor and major radius of the ellipse, dimensions are [2 1].
 N     Number of points on the curve.
 v1,v2 Optional parameter, two vectors pointing parallel to the minor and
       major radius of the ellipse, dimensions are [3 1].
