   Given:

      plane   a structure describing a SPICE plane.

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

              The structure has the fields:

                 normal:     [3,1] = size(normal); double = class(normal)
                 constant:   [1,1] = size(constant); double = class
