hat represents the limb of the ellipsoid
             observed from 'viewpt'.

              [1,1] = size(limb); struct = class(limb)

              The structure has the fields:

                 center:    [3x1 double]
                 semiMajor: [3x1 double]
                 semiMinor: [3x1 double]
