annulus_grid_test():
  MATLAB/Octave version 4.2.2
  Test annulus_grid().

annulus_grid_test01():
  annulus_grid() defines a grid of points
  with N+1 points on a horizontal or vertical radius,
  based on any annulus.

  We use N = 20
  Inner radius R1 = 1.000000
  Outer radius R2 = 2.000000
  Center C = (1.000000,5.000000)

  Number of grid points will be 980

  First 20 points:
   2.073171   5.000000
  -0.073171   5.000000

annulus_grid_test02():
  annulus_grid_fibonacci() defines a grid of N points
  

  We use N = 1000
