midpoint_fixed_test():
  FORTRAN90 version
  Test midpoint_fixed() on several ODE's.

predator_prey_midpoint_fixed_test()

  A pair of ordinary differential equations for a population
  of predators and prey are solved using midpoint_fixed().

  The exact solution shows periodic behavior, with a fixed
  period and amplitude.
