sphere_integrals_test():
  MATLAB/Octave version 9.8.0.1380330 (R2020a) Update 2
  Test sphere_integrals().

SPHERE_INTEGRALS_TEST01
  Estimate monomial integrands using Monte Carlo
  over the surface of the unit sphere in 3D.

  If any exponent is odd, the integral is zero.
  We will restrict this test to randomly chosen even exponents.
